Excellent puzzle game, truly flawless across the board! Sound design, graphics, etc, all excellent! I liked how there was a tutorial room to introduce each new concept, helped immensely with the flow of the game. I strive to be able to make something as simple and elegant as this some day! I forgot to mention the puzzle designs, they are great and well designed. They got too big brained for me a few levels after the cloning was introduced, but that's my tiny brain's fault, not the game's!
