I just played your game. You nailed the NES mechanics. Is there a way to get the source code. I wish to make a game but I can't nail the whip hit box mechanic and the stairs. There are a couple of things you may want to add if it does not affect the coding, Simon has a reverse jump in the original game. Essentially if you are in mid walk animation and quickly press in the opposite+up direction and jump he will do what is most likely the idea of a back flip. Other is a kneeling animation if he drops from a great height. Great work dude.
