A fun, clever puzzle game. Definitely play through co-op with a friend, as a lot of puzzles require you to control both buttons at points.

Most puzzles had multiple solutions, and there weren't any online tutorials for these levels. A friend and I had to sit down and think on how to get by an obstacle or solve a puzzle.

The gameplay and controls are responsive, but some of the collision can make the gameplay frustrating. There are moments you need to be a little too precise to get by an obstacle, which doesn't help when the buttons collision box are circular. It doesn't ruin the game, but it gives a game an additional learning curve that might get on your nerve in later levels.

Get it when it goes on sale. It's definitely a fun game. And it has a simple, but fun battle mode.
