For anyone who still cares:
It's a little bit extremely too late for me to have figured this out, but if you're having crashes, setting the game's affinity to only one CPU core through Task Manager should (I think...) prevent those.
Another thing that is also coming way too late (It's already been a year since the jam...), but the promised updated version is still being worked on, albeit unreasonably slowly; if the stars align it should be out before the end of February 2025. I'm giving up on the Mac version because getting the project working on MacOS seemed like a royal pain, so there'll only be Windows and Linux versions.
Don't expect anything huge in regards to this update though, it's mostly the same game but with considerably more polish and a little bit more content.
I might revisit this project in the future in the form of a spiritual sequel, but no promises.
(P.S. Never try to build off of game jam spaghetti code, it's a huge pain. Take the time to rewrite your game. Or don't. You're probably better at coding than I am.)
Update (July 28th, 2025): I promise that I'm not dead and haven't forgotten about this.
