I tried to play with a wired Xbox controller on the 64bit macOS version, and noticed that I could only navigate menus but not press buttons. Tried the tutorial but it only let me move around, I couldn't do any other actions, and then when I pressed Esc to pause and then tried to press the Quit button, the quit button didn't do anything. I had to force quit the app. I checked my plugin that lets me use Xbox controllers and it works just fine for other games, so it's not my computer. This game looks really cute but I will have to play later when I feel like a mouse and keyboard game. I think you should remove the Xbox controller input from the store page.
