One thing I would try to work on, is the instructions towards the player. I was reading it and trying to understand, yet when the game started, first 2-3 games I had basically no idea what was happening. But that might be just my issue being slow :D On the other hand, I must say that when I got into it, this is really cool idea! Just 2 screens were really fun and challenging, but when I moved into later stages ... well there comes real challenge. Great job, a certainly fresh approach to the theme combined with cool game idea.
