Nice job! This has a lot of potential. I found that a lot of the game consisted of trying to count tiles - I would create distinct floor tiles to make that easier. I also thought that the levels were too easy to sight read and complete first try. I think it might be interesting to go in a puzzle direction, where you have to figure out when and where you have to use your extra control periods, which I didn't have to do in any of the levels you made. Of course, there are other directions you could take this in. It's a good idea, but the level design needs some work. Great job!
