Boring...
But, I dont like these kind of games anyway....Got to lvl 100 before i stopped...had the screen cleared and was really bored. I liked the music though and that you have to keep going - not like a lot of other games like this were you have to keep waiting on blocks. I also liked that you could push just one side, inside of both coming out. Overall, I thought it was a good attempt at a bad game...LOL - again, I just dont really find these games fun.
So for what it is, its good.
