Incredibly fun; at first I struggled a lot with the easy difficulty but managed to clear the medium and hard difficulties on my first try :D
The artwork is super cute, and the UI is very polished (There was even a confirmation progress bar when I hit Escape to exit the game!)
Some of the cards could do with a bit more balancing (especially the Timing card; I think it’s a bit OP at the moment, especially if you combine it with cards that add time to the opponent’s countdown clock).
Overall though, I really liked the game and the wide variety of cards you managed to design in only 4 days!
