I resurrected an ancient UIUC x86 ASM game, built with some friends in the summer of 2002 for ECE291. Claude Code drove most of the work.
The first attempt was a full on x86asm->webasm transpiler which ran into some difficult stack issues.
The second attempt was successful via conversion from x86asm->c->emscripten->wasm [0]. It plays pretty well on mobile and just about any browser now.
Fair warning it is pretty difficult to win, unless you can figure out where the enemy weaknesses are [1].
