Fast N' Flipped Tetris!

Using my reverse-engineered Tetris game, I created an original spin: Fast N' Flipped Tetris

In this world, gravity has suddenly inverted, and now the classic pieces of Tetrominoes fly upwards! Complete 20 lines as fast as possible with inverted controls to win the game and reverse gravity to its normal state.

To play, use the controls to clear lines.
