There are a lot of butthurt reviewers on this game. "Oh, it's too hard!!! 0 stars!" "I only got past 2 pipes 0 stars way too hard!"
First off, it's not the author's fault if you find the game impossible, it's called challenge. And it's what a lot of games lack. Second, is it really necessary to give a 0 star review over something that little? When you give a low rating, you're supposed to provide criticism instead of being blunt and saying the game is too hard so it deserves 0 stars.
Sorry for the rant, anyways, the game is nice. It's very difficult and challenging, but half a star off because it is slightly laggy.
