Wasn't able to open the Mac download, and the error didn't provide anything more than "Could not be opened" :(
That is unfortunate. I don't have any means of testing on a mac and had to rely on godot's export :-/
My guess is godot doesn't support the newest MacOS update maybe. But its okay, I just booted up my old windows laptop to play. Your game is great fun and well polished! The controls can be a little frustrating sometimes though :P
