I am actually concerned with the vision for 4. I know that it's a rogue game and hence you need to know how to manage your resources/health and tactically decide which battles to take, however already I found 3 very challenging (especially the end dungeon) even when fully leveled up so if the aim is to make it even harder not sure how much fun it will be at t end.
On another note I do appreciate the idea of using more abilities more frequently as that would add a bit more strategic/tactical thinking to some of the gameplay
I guess wait and see :)
P.S. unclear on what's the upside of the Mummy: previously it was a way to heal without being limited by food - now it seems that the gains are not offset at all by the lack of ability to consume potions/mushrooms
