Cool game and quite innovative! I like how it all works, especially the fact that when I don't pass a level, my pattern doesn't reset, it stays, so I can modify it instead of starting from scratch, which is really helpful.
I also like the music - it sounds good, and how it fits into the gameplay. The graphics are nice too :).
Maybe with a co-op mode it would be even more fun to play :).
It was fun, congratulations!
