Even though this one is definitely the weakest of the trilogy, this one is still awesome. The concept itself is really interesting. I also like the fast-paced action, and the fact that the game can become easier as the player memorizes every detail.
One thing that could be worth mentioning is that only one theme for the level is used, being overworld. Also, the keyboard controls are a bit slow and do not fit for such a fast-paced game. One other thing I hate is how some bricks are placed in some parts where you'll have to restart the level due to some being placed below the ceiling and near a wall.
Still, a really great one.
