I like this game, it's pretty great. A few things I don't like are
1. The blocks you get at latter levels are all different that it makes it harder to make combine blocks, not to mention even making level 1 blocks because of the random spawner.
2. In latter levels you're being swarmed by mass units which introduced with low level blocks makes it extremely hard to defend yourself.
3. The little swarm bomb critters are overpowered, I can't get passed the first wave on level 11 in the abnormal zone without having all my blocks destroyed, and if that doesn't kill me the next waves do.
