I enjoy little puzzlers like this, I accidentally solved a few levels in ways I don't think they were supposed to be solved (level 4 i think comes to mind), the first one with the red mirrors I bounced them all over the place and it hit the moon. I do see the note on where to find the instructions, but it could be good if you can to put a instructions listing at the beginning as well. other than that i like the game, the space theme is great.
