Just an idea, but as someone who likes to play pokemon games with a USB gamepad, it would be really cool if it were possible to add some kind of support for that. it could be as simple as making it so that like in the normal games, the D-pad can be used to select attacks (not just the mouse manually clicking, as it currently is). Another option would be keyboard shortcuts for the 4 attack options, though that would be much clumsier as you would have to bind 4 gamepad buttons to 4 keys for that, which gets pretty cumbersome.

um...check the options dude, we already support all gamepads (apart from xbox 360/one controllers directly, but there are workarounds for them)
