Even though I was a beta tester, and I did have my beefs as a "self-considered" game designer with experience in action-puzzle, I am strongly considering buying a legitimate copy of the game to support the developers. The engine is incredible, and there's some very good puzzles in this game.
This is, essentially, the "new" gamer's generation of Lemmings. Although this may be optimistic, I hope it takes off or is remembered 10 years later as such.
