EDITED: Right after writing this comment and sending the report via app I have tried second time and it runs ;-). I closed and tried again to double check and I was able to play 3 levels of something. No crash, just didn't have more time currently.
I am leaving the original comment to encourage others to try again once or twice as it may work like in my case. There may be still some issue, not sure whether with game's build or Itch app. It is not that heavy nor I have any resource heavy app running at the time except the browser. So it shouldn't crash at all ideally.
Nice game btw. Definitely needs some polishing & fixes like flickering foreground elements having z-index fight.
--------------------------------------------------------
I had a problem trying to run the game on Mac via Itch app, just after installation. I am also preparing feedback via after crash form in Itch's app.
MacOS version: Big Sur v11.2.3
I haven't seen any specific reason in the crash report screen, but I might be missing something. Or maybe just the build is not compatible with this OS version. I see lots of complains in various places regarding recent development experience in macOS ecosystem.
Feel free to reach me to check a new build or discuss it further.
I'm glad you could play Matter! Yep, certain levels have some aesthetic issues like depth issues
Btw this Mac issue.. did you have to do something for the game to execute? This issue has been reported often, also I've never tried to play it thru the itch.io app, that's something I could definitely try, and the crash is not about performance, this game is not heavy at all, I think it's due to a permissions issue in Big Sur
No, I just tried again right after crash. The reason I have written a comment first and sent crash report via app was I had some issues with other games in the past, so I just though it will not run. I am glad I checked again.
I cannot help too much with Mac / Big Sur specific issues now except just checking a new build if you make one and ask me.
I am planning to resume my gamedev efforts soon, so maybe then I will have to dig more with my own projects.
I cannot find now the link to the report and I guess there is no UI for viewing them on Itch. There was some "stack trace" referring to a bunch of files, not sure if they were related to some parts of Itch's app or the game though. Do not have any response from Itch team yet.
