Great game. It's challenging but not too frustrating.

Music is great, graphics are nice and simple. The only thing which annoyed me were the controls. Especially when your character is divided to two smaller ones. It's almost impossible to do precise movements.

Other than that, there just few minor issues:

When you are divided and one of your blobs dies, the game should ask you to restart because it seems you can't finish level with just one half of your character.

The "R to restart" text rotates with room, so sometimes it shows upside down.

And you could tell the player that left and right arrows are moving by ten levels in the level selection menu.
