the first few levels made me think "dear lord, this is going to be boring". but I have to say that you strongly proved me wrong. The levels increase in difficulty in leaps and bounds. from it almost seems hard to die to a shameful 40 deaths in a level, lol. there are a lot of nice twists put in there(evil birds and hidden bats and playing with light and dark). It would be nice to have the opportunity to reply levels for a better score(perhaps a a save feature?). there was actually one level where an enemy ninja is needed to bounce on to get past(something I don't recall being explained in game btw), and he would actually kill himself on occasion forcing you to add another death to the toll XD. great game but with a few changes I would give this a solid 5 ^_^
