For some reason the opening settings page made me think this would be someone who just told claude to make a monkey ball style game.. maybe from seeing too much of that on HN. forgive me for that, this is awesome.
As far as i can tell it's not even an emulator or a decompilation running in emscripten or anything like that, they remade the game in TypeScript. love stuff like this https://github.com/sndrec/WebMonkeyBall
uh that code looks like claude to me
