it is very hard. i reached level 6. just got lucky and a lot of strategy. but it just reaches the point there are way too many enemies and they take the first turn and kill you. needs balance and checkpoints. overall, i love this game!
at stage 7 old mines, there is a glitch with the spider boss at the medium difficulty where she jumps up after a third of her health is taken, and she gets back down and is stuck and invincible. dwarfs just walk through her
