WebGPU is cool. It's exciting to me to see these things working with no download.
The actual js for this game is 130kb in all, though the music and sound effects bring the whole distribution to 10mb.
The original game is from CodeParade: https://www.youtube.com/watch?v=9U0XVdvQwAI
It can be a bit of a gpu buster, though it runs fine on my M1 Mac.
I'm experimenting with SolidJS+WebGPU+Vite as a game engine (https://github.com/grinstead/ambush). It's a pretty cool environment to develop in, but building everything from scratch is slow and developing at a hobbyist pace.
