I really like the idea! However, it's hard to really form a strategy with how many unknowns are in the game.
- I know how much damage I'll do but I don't know how much health the enemy has
- I can't see what cards are in my draw pile or my discard pile
- I don't get to see my hand until after I've moved
This could be a really cool game if you presented more info to the player so that they can make more informed choices. Still, very impressive that you managed this much in the jam's timeframe! Well done!
