Interesting game! I love how such a simple turn-mechanic can add so much to the game!
The art is good, and the mechanics are satisfying, and you're playing on nostalgia by using tetris, well done.
The only note I have is improving the controls, make them more smooth maybe? Also felt awkward to place down sometimes, in tetris you're able to slide in to fit spots at near end, that didn't seem to work well for me here (or maybe I'm just terrible at tetris?)
