Polished, well-scoped game, balance is good. Music fits well and doesn't get painful to listen to after repetition.
Possible improvements: If there is no time left and the cards cover up the end turn button then you are potentially locked out of progressing, I almost encountered this situation but not quite because the button wasn't 100% covered. Text is hard to read if not in fullscreen.
But overall I gave this game a very high score because it beats nearly all of the other games by a mile.
