This game is polished and good looking and you put a lot of work int it! But I kept hitting A out of habit and it really messed me up. You know what they say: don't fix it if it ain't broke. I'd use the standard controls for future games if I were you. Makes it a lot easier to play.
That said this is a brilliant take on the theme that I don't think I've seen before. You really did good here! Nice work!
Also I'd appreciate feedback on my submission if you get a chance!
