Found an issue where if I pause, my mana bar drops to 0 and doesn't recover. It did that yesterday, fine, I just didn't pause. Now, though, I'm just not given mana ever. Also, sometimes the heroes reset their specs automatically. Decently fun aside from that.
Love the game, but that scorpion boss is really random. I can only jump up, not forward, so I can only kill it if I was already jumping when it show up.
