I played until I get to defeat the terrible spooder. I had to go full aggro + stop her for the turn to be able to defeat her (I needed to replay a few times until I got this magical combination). I think it's a very interesting mechanic. But I would have like more meaningful cards (poison from the player, drain life attack, next attack deals more damage, discard to draw, make enemy attack itself, etc.). Most of the cards where just trade 1 cost for 1 damage.
