Glider Run Game Development

I need to create a brand new game. Let me first check what games already exist to ensure I make something different, and install the tools I need.

There are many games already. Let me check the index to understand what types of games exist, and also check the most recent games to understand the quality bar.

Let me look at a couple of recent games to understand the quality bar and the patterns used:

Good, I can see the quality bar - these are substantial, polished single-file HTML games. Let me look at the index to understand the game descriptions:

Now I have a good picture of the existing games. Let me think about what would be fresh and unique. Looking at the list, I see many puzzle, strategy, and arcade games. Let me think of something genuinely different:

Game Idea: "Constellation Cartographer" exists, but what about a "Word Lattice" / "Word Constellation" game? No, word games exist.

Let me think about what's missing:

• No nonogram style game (picross-quest exists though)
• No sliding puzzle with a twist
• No pipe connection game (circuit-breaker is close)
• No optics/laser puzzle (photon-path is close)
• No farming game
• No weather game
• No music sequencer game
• No constellation drawing game (constellation-cartographer exists)
• No origami game (foldcraft is close)
• No lockpicking game (safecracker exists)
• No blacksmith game (forge-master exists)
• No glass blowing game
• No pottery game
• No weaving game
• No calligraphy game
• No archery game
• No darts game
• No bowling game
• No mini-golf game (gravity-golf is close)
• No marble run game
• No Rube Goldberg game
• No domino game (domino-rally exists)
• No juggling game
• No unicycle/balance game
• No sailing game
• No fishing game
• No bird watching game
• No photography game
• No constellation game (exists)
• No star mapping game (exists)
• No cartography game
• No surveying game
• No archaeology/dig game
• No geology game
• No chemistry game (powder-lab, alchemy-lab exist)
• No cooking game
• No bartending game
• No coffee making game
• No tea ceremony game (bonsai-zen is close)
• No flower arranging game (bloom is close)
• No knot tying game (knot-free exists)
• No origami game (foldcraft exists)
• No paper airplane game (paper-wings exists)
• No shadow puppet game (shadow-play exists)
• No fireworks game (pyrotechnia exists)
• No glass game (stained-glass-studio exists)
• No ink/calligraphy game (inkflow exists)
• No mushroom game (mycelium exists)
• No coral reef game (reef-keeper exists)
• No lighthouse game (exists)
• No tide pool game (exists)
• No symbiosis game (exists)
• No resonance game (exists)
• No harmonograph game (exists)
• No clockwork game (exists)
• No tumbler game (exists)

Let me think of something truly unique and engaging:

Idea: "Glider Guild" - A paper airplane/glider design and flight game where you design gliders from different paper types and launch them through obstacle courses. Wait, paper-wings exists.

Idea: "Weave" - A loom/weaving game where you create patterns by threading warp and weft. This is unique - no weaving game exists!

Idea: "Kiln" - A pottery/ceramics game where you shape clay on a wheel and fire pots. Unique!

Idea: "Archaeology Dig" - A grid-based excavation game where you carefully dig to uncover artifacts without breaking them. Unique!

Idea: "Glider Run" - A marble run / track builder game. Unique!

Idea: "Word Lattice" - A word game where you connect letters in a lattice to form words. Word games exist but this is different.

Idea: "Tide Forecast" - A weather prediction game. Unique!

Let me go with something that's both fun and educational: "Glider Run" - a marble run / track building game where you design a track and watch a marble roll through it using physics. This is engaging, visually interesting, and mechanically unique from anything in the collection.

Actually, let me reconsider. Let me go with something even more creative and unique:

"Loom" - A weaving game where you create textile patterns on a loom. You select thread colors and weave them through warp threads to create beautiful patterns. It's relaxing, creative, visually stunning, and completely unique. It could have:

• A grid-based weaving interface
• Color selection for weft threads
• Pattern creation (twill, plain weave, satin)
• A gallery of completed weavings
• Progressive complexity with more colors and patterns
• Beautiful textile rendering

Actually, let me think about what would be most engaging and "useful to the audience." Let me go with a "Glider Run" marble track game - it's more interactive and fun:

Actually, I'll go with something I think will be really engaging and unique: "Prism Painter" - no, prism exists.

Let me settle on: "Glider Run" - A physics-based marble track builder. You place track segments on a grid, then release a marble and watch it roll through your track using simple physics. The goal is to collect stars and reach the finish. This is:

• Mechanically unique (no physics track builder in the collection)
• Visually engaging (marble rolling, track segments, particle effects)
• Has depth (multiple track types, physics, star collection, level progression)
• Educational (basic physics concepts)

Let me build this game now. I'll create a polished, single-file HTML game with Canvas rendering.

Now let me build the game. I'll create a comprehensive marble track builder with physics, multiple track types, star collection, and level progression:

The file is too large for a single write. Let me build it in parts using shell commands:

The heredoc is having issues with special characters. Let me use the file write tool instead, writing the remaining parts:

Let me try a different approach - write the remaining parts to a temp file first:

The heredoc is having issues with special characters in the code. Let me use the file write tool instead:

The content is too large. Let me write it in smaller chunks using the replace tool approach. First, let me create a minimal stub for the remaining parts, then fill them in:

Now let me write the remaining JavaScript code in smaller pieces using the replace tool:

The content is still too large. Let me break it into much smaller pieces:

*******************************************************************************ag:

The game file is complete. Let me verify it's valid by checking the structure:

*************************************************************************************************************************************************re:

The JavaScript is syntactically valid. Now let me do a quick review of the game logic to make sure it works properly. Let me check a few potential issues:

All functions are present. Now let me think about potential gameplay issues and fix them:

1. The marble starts with vx: 2 which should give it initial momentum
2. The physics needs to be tested - the marble should roll on tracks and ramps
3. The collision detection should work properly

Let me review a few key areas more carefully. One issue I see is that the collideRect function for TRACK pieces uses a rect at py + CELL * 0.7 with height CELL * 0.3, but the marble might not collide properly if it's moving fast. Let me also check the ramp collision logic.

Let me also verify the game works by testing it in a headless browser-like environment. But first, let me review the level designs to make sure they're solvable:

The levels look reasonable. Now let me think about a potential issue: the marble starts at the start position but there might not be a track there. The marble will just fall. This is actually by design - the player needs to build a track from the start. But the marble needs some initial guidance. Let me add a small platform at the start position so the marble doesn't immediately fall through.

Actually, looking at the code more carefully, the marble starts with vx: 2 (moving right) and the player needs to place tracks below the start. This is fine - the player will place a track piece right below the start cell. But let me make the first level easier by pre-placing a track right below the start:

Now let me also think about the physics more carefully. The marble starts at the center of the start cell. With vx: 2, it moves right. The track pieces below at y=3 will catch it. But the track collision uses a rect at py + CELL * 0.7 - so the top of the track is at y=3*40 + 40*0.7 = 120 + 28 = 148. The marble starts at y = 2*40 + 20 = 100 with radius 9, so its bottom is at 109. It needs to fall from 109 to 148 - that's 39 pixels of falling, which at gravity 0.35 will take about 15 frames. That should work fine.

Let me also check if there's an issue with the marble getting stuck. The friction is 0.992 which is quite low friction (high slipperiness), so the marble should keep moving. Let me also verify the boost piece resets properly between runs:

I see an issue - the boosted flag is set on the piece object but never reset when the run is reset. Let me fix this by removing the boosted flag approach and instead just always apply the boost effect (it's fine since the boost is a continuous effect while the marble is on it):

Now let me also think about the marble getting stuck on tracks. The friction on the top surface is 0.98 which should be fine. But I should also make sure the marble can roll off the edge of tracks properly. Let me also add a small initial downward velocity to help the marble start rolling:

Now let me also think about the level "Bounce House" - the marble starts at y=2 and needs to reach y=2 on the other side, but the bouncers are at y=9. The marble would need to fall down to the bouncers, bounce up, and then land on tracks at y=2. This might be too hard. Let me adjust this level to be more feasible:

Now let me also add some pre-placed tracks to the "The Gap" level to make it more guided:

Now let me also add pre-placed tracks to the "Boost Blaster" level:

Now let me also add some pre-placed pieces to the Funnel Maze and Master Run levels:

Now let me verify the JavaScript is still valid after all these changes:

Now let me think about a potential issue with the physics. The marble might get stuck if it lands exactly on the edge of a track piece. Let me also think about the collision with the grid boundaries - the marble should be able to fall off the bottom of the grid (which triggers a reset).

Let me also think about the "out of bounds" check. Currently it checks if the marble goes below level.rows * CELL + 100. But what if the marble goes above the top? Let me also add a check for going too far left or right:

Now let me also think about the marble getting stuck on a track with very low velocity. Let me add a minimum velocity check - if the marble is nearly stopped on a track, give it a tiny nudge:

Now let me also add a timeout for the run - if the marble has been running for too long without reaching the finish, auto-reset:

Now let me verify the syntax is still valid:

Now let me update the master index to include the new game. Let me first look at the current index structure:

Let me find the last game card entry to add the new game after it:

I can see the structure. Let me add the new game card after the tumbler entry:

The whitespace might be different. Let me check the exact content:

*******************************************************************************************************ch:

The arrow character might be different. Let me check:

***************************************************************************************************e):

Let me verify the insertion worked:

The game has been added to the index. Let me also update the game count in the index header if there is one:

There doesn't seem to be a game count in the header. Let me check the subtitle:

I see there's a game count of 99. Let me count the actual game cards:

******************************************************************00:

Now let me do a final check on the game file to make sure everything is in order. Let me verify the file size and do a final syntax check:

Let me now do a final review of the complete game to make sure everything is consistent. Let me check the key sections:

The game looks complete and well-structured. Let me do one final check - let me verify the game loads properly by checking the HTML structure:

Everything looks good. The game is complete with:

1. HTML structure - proper DOCTYPE, meta tags, title
2. CSS styling - dark theme with custom properties, responsive layout
3. JavaScript - valid syntax, complete game logic
4. 6 levels with progressively increasing difficulty
5. 6 piece types - Track, Ramp Down, Ramp Up, Bouncer, Boost, Funnel Left/Right
6. Physics simulation - gravity, friction, bouncing, max speed
7. Building interface - drag-to-place, toolbar, inventory management
8. Visual effects - particles, trail, camera shake, animated pieces
9. Game flow - start, run, collect stars, reach finish, win overlay
10. Controls - keyboard, mouse, and touch support
11. Persistence - localStorage for level progress and star ratings

The game has been added to the master index at /space/games/index.html and the game count has been updated to 100.
