Hi, thank you very much for the feedback! I am sorry your controller didn't work :(
Maybe it was a little bit misleading to say that we supported the X360 controller. Actually, our game supports it just in the Windows platform.
For some weird reason, button mappings change according to the controller (even though PS4, X360 and XONE controllers have similar designs, 'Joycon Button 0' maps to different buttons in all of these controllers), the operating system and even according to the way it is connected to the computer (bluetooth or USB, for instance).
This problem might be solved depending on the tools you're using or if you implemented all these possible mappings yourself. As we're using Unity, our possible solutions right now are: use the new Input System (beta), buy a plugin in the Unity Asset Store that solves the problem or figure out all the possible mappings and hardcode them in our game. We have the goal of using the new Input System but we couldn't make it work in time for the demo :(
That said, we'll work hard on fixing this issue as soon as possible and update the demo :) Hopefully, with the new Unity Input System, we will support all sorts of controllers in different platforms!
