This seemed like it was just a simple matching game at first. It really was more interesting than I imagined. I was amazed at how it got hard at all. I mean, it seemed so easy at first. The music is quite good. I think you could have had some better designs, though. I appreciate how unique it is.
It's pretty hard because you don't have a good look at what's going on. They disappear right offscreen. I guess that's not really a problem. That really only happens when you beat the level. It's still pretty challenging, though.
