Cute little game. I wish there was some music to it. It took me a minute to realize how the curse theme went into play, but I thought it was a good implementation of the theme.
I think I would love to see this as a time-trial kind of game. The levels seemed a bit too easy for me, but I think a way to fix that would be to just make the curse happen more often so you really have to book it through the level before you become too cursed and can’t jump/fight any more.
Good start though!
