This is great! I have one bit of feedback, which is that the controller bindings are too limiting. In Deltarune itself, A, B and dpad right all activate the right key, and Z, X and dpad left activate the left one. Since using the triggers/shoulders is uncomfortable for me, I have my right thumb on A and left thumb on dpad left for fastest inputs. In this version none of those buttons seem to work, only the triggers/shoulders. If you could take a minute to add support for the extra buttons, it'd be greatly appreciated.
