The 64 bit Mac version is a .exe. Also I am unable to use my 360 controller running the 32 bit version.
Hi! I just checked and the 64bit Mac version is indeed a dot app. Itch.io downloads can sometimes get funky, try downloading it again! If the controller still doesn't work there, let me know. I can try building the game with a different version of the engine to see if it helps.
