This is a cool game!
I like how much combat this game managed to squeeze into a weekend. There are lots of different maneuvers and I like the idea of discrete rooms. It also seemed like I could get bonus points by getting more coins. It's a cool game with lots of neat combat. Nice work!
Good news: I got this working on mac just now. I’m on Mac OS X Big Sur 11.5.2 on a 2017 macbook pro. I moved it to my desktop and then ran these two commands and then it worked great:
sudo xattr -r -d com.apple.quarantine "/path-to-game/Godot\ Testing.app"
sudo xattr -cr "/path-to-game/Godot\ Testing.app"
I hope it works for you and others too.
