The controls seem a little finicky to me for some reason, but otherwise it's quite fun! It's a neat concept, and the only things I can think of improve would be a clearer explanation of how the "face" blocks work (I still don't fully understand the mechanics behind them after beating the game), and adding a restart button since it's very easy to create an unwinnable situation. (This isn't a huge issue thanks to the ease with which you can die, but it would still be nice.)
