Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.
For more info you can refer to the repo - https://github.com/gnikoloff/wasm-snake

Smolnes: A NES Emulator In
Big fan of this author's work.
They have a Gameboy emulator written in C, which can be compiled to WASM and run in the browser.
https://github.com/binji/binjgb
I learned a lot from the code.
Also I love this project with a bunch of demos in hand-written WebAssembly Text (WAT) format, which is like low-level Lisp that works only with raw memory, numbers, and minimal syntax.

Then I discovered the same author is quite active in the WebAssembly ecosystem, including specs and tooling. Fascinating stuff!
