Classic Snake in Direct WebAssembly Text

All of the game graphics, state and logic are written in WebAssembly Text. The host environment (Javascript) is responsible for:

Game tick loop

User input

Providing characters "0123456789GAMEOVER" byte data on game startup

Blitting the pixel buffer to the display with WebGL2

The game uses 3 virtual pages of memory (64kb each) for a total of 192kb. Within those exist the pixel buffer contents, the characters data and snake positions. For more detailed breakdown you can check src/snake.wat.

The memory is shared between WASM and JS. On each game tick, the pixel buffer region of the memory is transferred to a WebGL2 texture, uploaded to the GPU and blitted to the screen.
