Confusing, but I had fun when I figured it out.
The main thing I noticed about this game was the lack of explaining towards why the jumps were controlled with four buttons, instead of just one. The button you press to jump with has to match the kind of obstacle you're trying to clear. Had a bit of trouble telling the difference between the left and right type of obstacles, but since there are only four levels I think it was made that way to be challenging. Thanks for the huge life bar.
