I tried the game on several devices. On desktop it works well with a keyboard, on Android it works well with a bluetooth controller, but on Android TV it does not respond to the same controller (it works in the smartbox menus, but not in the game). Maybe it's because several bluetooth devices are connected (it responds to the remote control, for example)? Couldn't there be a screen at the beginning of the game saying "press a button on the controller you want to use" (I've seen such a solution in other games), I don't think it's that difficult to program this (although I don't know Godot in depth).
Otherwise the game is great, 5/5. :)
