As everyone else is saying, This isn't a game. not even would I consider this a prototype. Although your graphics are nice, this isn't the time (or place) to submit this. Put it on your dumping grounds or at least submit something more of a game.
As for your actual game, a few things :1-platformers are easy to program, but do something to make it stand out. nothing sucks more than a generic boring platformer. 2- you gotta fix your controls. my character slides around like the level is an ice rink. to fix that, you may want to either lessen your strength of the button pushed or increase the friction of the ground. Good luck on your game making.
