With blocks coming from both sides of the screen, the game has a unique challenge. I've probably wasted about 6 or 7 hours on this game, all of it greatly enjoyed. The time I put into shows however, because I just got the highest submitted score ever.
Probably not for you if you don't like arcade type games where the goal is to get a good score.
Stars off for having the some rewards of the achievements be unclear, I still haven't figured out the supposed "burner" feature. I thought it might be a new block like the time stop thing was but it doesn't appear even in the upper 200 column levels.
