I may have found a bug, or I completely misunderstood how the cards work. I am at the (I think?) last stage in the last level and when I have 2 emotional, and use the card that zeroes the cost of two next played cards. Then I wanted to play the card that costs 2 emotional, it should have been free, but it killed me. Twice already, because I thought I just missclicked and didn't use the "make-it-free" card. I'm not sure if I have the energy to try again..
Either way - the artstyle is really fun, music is very good, too. Not sure about how the game fits the theme, I guess I would find out if I was able to finish the game. Really nice entry though!
