Heya, did you 100% download the intel build? Unfortunatly I can't easily test this since I don't have a mac but my understanding is it shoooould work, but if not I can see what I can do : )
Investigated this with Liana (the engine developer) and it seems to be some kind of odd code signing issue which is upsetting apple. We've uploaded a new build, please try downloading this via the itch io app, as the game seems to run correctly on apple silicon but ONLY via the app. We have no idea why this has changed. Let me know if that works for you please : )
