Challenging!
I've played this game a million times and it never gets old. I'm absolutely in love (haha). Very challenging at times. Some took me a good 10 minutes to figure out (and then there was the good natured "Why didn't I try that first!?" frustration). I'm so glad you made a sequel!!
To KawaiiBianca: I dunno what game you're playing...3D Logic didn't have 50 levels. It had thirty. :P :P
