As always impeccable mechanics, a clever idea, soothing music and a thoroughly enjoyable game overall.. but for those escalating difficulty levels!!!
Can't seem to get past level 18 right now no matter how many tries I give it. Will try with a clear mind later. Really impressive how such a seemingly simple thing can be so mind-boggling...
Thorough work on the levels. Plenty of variation. Good graphics. It really is a puzzle game too!
