Didn't quite understand what was going on in my first run, but managed to wake up (thrice) in the second. Should've looked at the known bugs since I was definitely trying to play really fast and some of the cards went haywire haha.
The design of the game is quite elegant, although there seems to be one clear dominant strategy. I had fun with it. One small suggestion would be to indicate that the player can't wake up just by the depth, because I tried rushing that and it kept saying "Can't Wake Up" and no explanation why.
The art pieces of the cards and enemies is really cool, was enjoying looking forward to what kind of a monster shows up next! I think some interface adjustments would help showcase the art better and also explain the game nicely.
