Amazing atmosphere! It's fun to see the progression of this game over the rounds, but I'm not sure where it's going. I can't put my finger on exactly why, but the gameplay feels a bit disjointed? I like the realtime aspect of it, but the essence and sacrifice mechanic don't really do it for me. It currently seems like the best tactic is to spam as much as possible onto your first hero with all the starting essence you have, and keep drawing and playing cards while you can. And then just wait for the game to play out with you winning because the 30 second 0 damage enemy can't touch your triple hitter with 5s cooldown.
But still, awesome game, good stuff :D
