I really liked the concept of this game, it has more originality than the regular match-3-by-switching-their-position type games. Made a small donation, certainly not regretting it. It was a bit on the easy side but also had it's share of harder levels as well. But I'd rather have it "too" easy than have the difficulty level so high I just get frustrated and give up, so not a major problem. Slightly disappointed that the sequels took a different format (though they are by no means bad games themselves either!), would love to see a more mechanically direct sequel to this! Well done guys! :-)
