Very fun game! I enjoyed it! An improved Tetris! I don't know if it was just my screen, but It was a very tiny screen! It would be much better to play it on full screen. Having that in mind, the letters were too small and had no contrast! Improving that could enhance playability and the readability of the controls menu. Also, I'd include a tiny hint with the controls and type of tiles, but it's just a matter of opinion.
