Cookie D'oh!
A C64/Amiga-era arcade game about accepting every cookie the Internet throws at you. A complete game on the toolkit, native and web from the same code.
- Keyboard play
- Gamepad / touch supported
The toolkit
game-toolkit
Small, focused Rust crates for 2D and 3D game jams.
v0.11.3 EUPL-1.2
Implement init, update and render, and ship. A batched 2D painter (sprites, shapes, text, tilemaps, optional vello vectors) and instanced, depth-tested 3D meshes draw into the same frame, so a 3D scene gets a 2D HUD for free. Native and the browser from the same code.

Built for the browser from v0.11.3. Click into a running demo for keyboard input.
Features
What it does.
One frame, 2D and 3D
Sprites, SDF shapes, glyphon text and atlas tilemaps through one Painter; instanced meshes with depth testing under it. Draw order is the order you call.
Browser from the same code
wgpu on WebGPU with a WebGL2 fallback, WebAudio, the Gamepad API and touch. Assets preload from a manifest so loading stays synchronous.
Sound that just works
kira playback that degrades to muted without a device, plus synthie chiptune music and effects behind the synth feature.
Pull only what you use
Core, gfx, input, audio, assets, Aseprite, ECS, egui overlays and GPU compute are separate crates behind one umbrella and its features.
Jam templates
cargo generate a 2D or 3D starter with assets, a web build and an agent guide to the whole API already in place.
GPU compute
WGSL kernels over a grid, ping-pong storage buffers, a readback ring that never blocks, storage textures you draw like sprites, and a submitter that keeps simulations off the frame. Behind the compute feature.
Post and palettes
Virtual resolutions, a CRT filter, custom WGSL effects and indexed colour with palette cycling, for the retro look without fighting the GPU.
