Wow, this one has me impressed!
I feel like this is the kind of game you might see on youtube! I think you did well to create the laid back atmosphere of a lounge in hell that fits really well with the nature of the game. You also did a great job making it intuitive to play, I understood the rules without even reading the instructions! And I won't spoil it for others, but I really liked the final twist - the music changing was a nice touch. My only criticism is that the text about each new ability disappears too quickly to read it all.
Honestly, this is one of my favorite games I've played so far! I think with some more development this could be a really interesting full length game! I really enjoyed the relaxed story experience, our game is I suppose the opposite end of that scale, you should come check it out!
