https://divVerent.github.io/aaaaxy/ A nonlinear puzzle platformer taking place in impossible spaces

This one uses Go. Known to run on x86, x86_64 and arm64, but likely will run on anything with OpenGL. Excluded s390x though, as the automated check ran out of memory multiple times there, meaning it's probably unlikely this game will work well there without swapping anyway.
