good game... way too many bugs!
I have no problem with the difficulty, its just that some bugs got in my way. there is one level where you have to slide under some rocks followed by a steep downhill slope... i got tired of using slide and flying through the air perfectly straight, and smacking into the building. or another level where there is a slide right at the end and you smack into the cliff about 70% of the time, because the ninja does not run down hills, he falls.
