Some times a headache.
While I didn't play the entire thing. I played enough to know the main formula for the game. Some few pointers I want to add.
1: It got really annoying trying to hold down the X button to slow down time. It should be more of a toggle.
2. I don't know if down the road you get different abilities. But checking out the number of rooms you would have to play, it would get really boring with just spitting out pink blocks.
