Stanislav Merezhko recently introduced a game called Doptrix to the Android Market. I have to say that at first glance, I wasn't expecting anything brilliant. I was mistaken.
Doptrix turns Tetris-like gameplay on its head, literally. The game uses a familiar four-block shape pushing premise, but allows the player to turn, rotate, and flip the game board as they choose. The player can also choose when (and from what position) a shape launches toward the board.
