WOW! beautiful game, really enjoyable to play, i would usually get through about 10 levels at a time, get stuck on one, get frustrated, quit for a few days, come back, succeed, then get through another bunch of levels before getting stuck and repeating the cycle again, so it was the PERFECT level of difficulty for me, and i really enjoyed the kind of physical nature of the puzzles. Excellent game! Excellent work! thank you for sharing!
