This is a classic version of Tetris, but with its own unique mechanics and improved controls. I'll start with the controls. Player 1 controls: A, S, D - move and quick descent. Space - rotate the piece. Enter and ESC - pause. R - play again (only effective when losing). Keys 1, 2, 3, 4 - special action (new game mechanics). Player 2 controls: Arrow keys - move and quick descent. Right CTRL - rotate the piece. Numpad 5 - pause. Numpad 0 - play again (only effective when losing). Keys numpad 1, numpad 2, numpad 3, numpad 4 - special action. (new game mechanics). In 2-player mode, each player has their own pause. Enter and numpad 5 are used for individual pauses. ESC - global pause (pauses both players) A special game mechanic is stars. To earn them, you need to make a combo of 5 or higher. To start accumulating a combo, you need to cut one line with each new piece. If you make 5 combos, you get 1 star; if you make 8 combos, you get 4 stars. With stars, you can use special mechanics; earned stars can be considered a reward for your efforts. What do stars do? Having them unlocks special action keys. Using stars allows you to delete the current piece (key 1), remove the piece but also the blocks it lands on (key 2), mirror the piece (key 3), or disintegrate (the landed piece will disintegrate into individual blocks if there are empty squares on the playing field beneath it when you place it). At the end of the game session, player statistics are entered. Only the game highscore is saved. In 2-player mode, the high score is displayed. During the game, only the player with the higher score is shown, and it changes in real time.
