I didn't care much for this game. It seemed like it was just you looking for green beams. Heh heh, that sounds like green beans. It did get more interesting when the enemies came in. I still have to give you credit for having a pretty original idea. It just doesn't work well.
It just seems like the same thing over and over. Granted, I wasn't too bad at it. People more familiar with the game should enjoy it more. I really do need to start reading the author's comments. It's at best passable.
