Cool!
Well, it's been a long time since I've left a review, but I felt this needed it.
I played that for ages. I got to level 15, but gave up when I ran out of ink. Very cool game indeed. Some levels were mega hard though. Let's see... 13, 14, 15... they were all very hard levels. But, I love hard levels. That sense of satisfaction once you complete one reminds me of Super Monkey Ball. That would make a very sweet DS game, by the way.
Graphics: Minimalist art, though it fits the bill perfectly.
Style: It plays very well and smoothly
Sound: That can be pretty annoying when you're trying to nail those tough levels. A heart "thump thump.......thump thump.......thump thump" would be retty cool, lol.
Violence: Uh... no.
Interactivity: Hm... let me think.... 10/10?
Humor: None
Overall: 9.3
Anyways, the point is that that was a very great game, and I reccommend it to puzzler fans.
