I guess I'm going to show bias by saying I didn't enjoy this because I wasn't good at it. Even looking at the walkthrough, I couldn't understand it. Level 5 is the one I can't get past. It just doesn't seem that interesting to really care about. I guess the layout is nice. The music isn't bad.
It just did little for me. I need more straightforward gameplay. Well, maybe this was too straightforward. It just had little variety. It wasn't rewarding.
