Great.
Very simple and fun to play. Even better than the game that inspired it. Good Music and easy to use controls with simple and easy-to-remeber combos. Checkpoint codes are well spaced. However this game would be improved by... just a little more. It sort of lacks a reason to replay it more than once. If you ever decide to do a sequel or add things to this game. I would probably add medals and things to collect. Just simple stuff like that. That alone would make the game more interesting and fun to play. Just suggestions...
Anyway, really great job! 5/5 10/10 Favorited.
