the game crashes for me after the opening cutscene (?), in case that's happening to anyone else as well.
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.
