Thank you! As mentioned by Denowq (the other dev) under other posts. Balancing is very hard thing to do and we've spent a lot of time balancing the cards, so they make sense. But because of the time pressure, we had to mainly focus on the game's features and balancing had a smaller priority, though we tried our best.
We are looking forward finishing this game up after the Jam, so everything will be more polished! :)
