I tried to like it, I really did. A good game needs the right balance of fun vs challenge - this one goes beyond challenging to frustrating. The controls are too tight requiring absolutely perfect timing making completing level 19 or beyond require 50+ attempts. As a side note it is a bit silly that a ninja gets killed repeatedly by bumping into a stone block. Note to the creators - bouncing back off the stone or being able to press the jump button a second time to do a flip and gain height would really make it more fun.
