Good game, very addicting! But it would be so nice if you added more ways to get rid of poisoning. I got through level 15 with 0 damage, but then the poison got me again. Levels past the final boss also kind of feel like a chore, but I'm sure it won't be a problem as you add more content to the game.
Here's my built more or less, whetstone + spiked helmets + haste-adding armor make you feel like a god at turn 10
