I'll look into the controls. With regards to the theme my though would be fake floors that you fall into and also the multiple portals as opposed to the winning portal. Thanks for the feedback, If you don't mind me asking what did you find wrong with the controls?
Well, for starter: the character shouldn't get stuck on slopes. You could also improve the jump curves, which is the rate where the player goes up and down during jump. This can improve the game feel immensely.
