Flip Flop

Rather bland, kind of strange. Each piece is four cubes, two one color, two another color. You can change which two are which, but not, as far as I can tell, rotate a piece, only move them left or right. Careful though, because if they touch something above them they stop falling. There are no instructions, and no list of controls, so I could easily be missing something. If you get four of the same color touching, they vanish, but the others touching it do not fall. Kind of tricky to stop them fro rapidly reaching the top. I did have a strange issue with my computers anti-virus freaking out while installing, not sure what it is trying to do, but I don't like it. That is probably fifty percent of why I give this one a thumbs down. The other fifty percent is that it really does seem very, very basic and simple, like a more primitive version of Tetris. Even being able to rotate them might help, not sure. There are no power-ups or anything to spice things up or mix them up. Meh...
