You did good. Best parts are combat, music and that it's actually 2D game (saw from a comment). It looks so much like 3D =)
I try to find bugs too. The graphical one is that the jail bars aren't rendered if you look them from sides and not directly facing those. Another one happened when I tried to use the smiley item. On first use nothing seemed to happen. Then I tried to use it again and got this error.
