I love the game right now. made me get into rythem games =) only problem is that It feels a bit uncomfortable using the arrow keys or wasd. The problem with it is that the arrow keys are too narrow and i'm not left handed so wasd is hard to use.
What I'm proposing is add a settings menu or something where you can change your keybinds or at least add "AS-KL", "QW-OP", or even "ZX-NM" as viable keys. It's usually used in other games and would make FNF easier to play.
