Thanks for the feedback!
- The thing with the gold indeed requires some fix so it's not useless when you don't have enough Deaths.
- I suppose on the level 7 and 8 you have got to the shop chamber. It's nothing but food that restores some HP, and the more pricey the dish the more it regenerates. Currently, there is no difference in this chamber and these items' stats whether you got to the shop on level 8 or 20; there's no level progression at all in the game at the moment.
- Thanks for pointing out the narrow corridors! I think the same, they should be wider.
