The graphics and the music are good, but the control issues made me quit at the 3rd boss. Sometimes it doesn't register the buttons I pressed, sometimes it double jumped when I touched on a ledge. Everything got worse when I got the stick on walls powerup. I jump, I touch the wall and the game imediately jumps me in the opositive direction. Or just don't register my second jump and I got stuck on the wall. Frustrating.
