I really enjoyed this game!! The character design and level design is phenomenal, my favorite card ha to be the sword because that fits my style of play the most. Amazing concept that would lend greatly to being extended upon with a full collection system like a real TCG. I'm no game designer but an avid player of games, but my idea is having a roster of characters/cards (I know it may be hard but maybe 20+ unique fighters) where you play an opponent with your deck of 6 or some number in a series 1v1 elimination rounds till one player is out of cards.
Overall Amazing game and enjoyed my time playing it!!
