Never really done anything like this before, kinda difficult at first but I got the hang of it, my bean is very easy to animate because no arms or hands or mouth, good starting point I think. starting keys: ASL; press space to change key binding press B to enable/disable botplay
By the way, you cant hold them down but you can still just mash all of the keys at once, it should count as a miss if you press a key that isn't touching an arrow.
