I’ve thought a tiny bit about this. I think I’d lean towards Guile for a game because of Hoot, wasm compiler, and Chickadee, little game library. But I’m remarkably unqualified to have a real opinion since I’ve used Chicken for 72 hours now.

I am currently looking into simple options for using Scheme as a scripting language in a game written in C. So far, s7 made a good impression for embedding it, but I am also not that far into evaluating the actual performance. I looked a bit at Chicken, and it seemed possible to embed, but too complicated for my purposes.

There's raylib and sdl2 eggs available. Those are a great place to start.

I've only made the one game with it. A lot more GUI apps.

sdl is in the package manager, making it fairly easy to hook into, and "standard". From there its about the same as anything else.

Because I was cross-compiling, I compiled to C and had a... Somewhat complicated Makefile for building Linux, Windows, Android binaries all at once.

Debugging Android made me give up, in the end. The platform, not the tools I had, was the pain point.
