Wow, this was a lot harder than I thought. Well, mostly by Level 3. It isn't that good for me to want to really work that hard. It's still a very playable game. I have to look harder into it. I wasn't even aware of the rules at first!
I thought the map was a level itself! The design's pretty good. Sprites should still be around. It's a pretty original idea when you think about it. The colors are nice.
