this game has an interesting concept and is surprisingly fun
there are minor flaws thoughb
1. the text is unnecessarily wordy, the tutorial part has a ton of unecessary details, even after defeating an enemy it says "Victory: Boss ran out of health". those types of details are better explained through visual feedback
2. could replace the " health bar" with a deck of cards and an animation that when taking damage, cards fall off or go to a graveyard slot
with that being said, great job man the concept is fresh. goodluck!
