The controls and speed were fine, but this scrolling technique is kind of.. annoying, especially during jump. This scrolling also generates some "leap of faith" scenarios which sometimes turns out to be the right thing to do, but most of the time you just die miserably. This guessing game could even be okay, but starting the screen over and over agian just to find the spot to fall down is a bit too much punishing to my taste.
Music, sound, the character animation and the overall feel was cool!
