This is pretty cool! For what it's worth, I think there are a few small things you could do to make it much more intuitive:
- Make the player cards look different from the enemy's, with symbols, card design, or color (be aware of accessibility for colorblindness though!)
- Make the icons in the dungeon have more obvious meanings. Like crossed swords for battles, and adding a " " symbol on the new cards
- Make some sort of sprite to show where the player is in the dungeon
Nice work! :)
