That 's most likely an issue that Unity has with some controllers, specially DualShock. Try to unplug it and see if that's fixes it.

That's odd, the only crash I've ever heard about was one on startup due to another program (citrix) messing with unity games. That I can remember it has been tested on W7, 10 and Proton (Steam Deck). If you're using a different OS or a 32bit one it could be the issue. Beyond that, driver incompatibilities are unlikely to be the problem but who knows. I'm sorry but I'm not sure if there's much I can do about it.

Hi, I don't think I ever tested the game on x86 and I'm no longer working on this game so unfortunately I'm currently unable to make this happen. You can still download it for free on the store page below through the Google Drive link there however in case you want to try it.

Hi, purchases through the bundle don't include a Steam key. It's not up to me, it's and itch.io thing, sorry.

From the Bundle page:

"Please note: No Steam (or other external keys) will be given for bundle purchases. Only direct downloads will be available on the itch.io page."
