The game looks really fun, but it didn't quite work right with my Xbox One controllers on a mac. The player was always moving up, pressing down caused us to jump.
I would definitely try again once Xbox One controllers work! :)
Sorry to hear you had a problem with your XBox One controller on the Mac. Unfortunately I don't have a XBox One controller to test it out and work out a fix. You can always play two players on the keyboard controls though, that is until I raise some money to buy an XBox One controller, so I can fix what ever is wrong.
This is the one I'm using: https://github.com/360Controller/360Controller/releases
