I went up to 10th level or something, where there started to be several enemies of two kinds in each level. I made a bow just before dying, up to there I only used an axe and potions. I just checked the recipes, maybe I would have managed to make a sword or spear now that I thought about trying the hold on something else to make a bow, not certain.
The game works pretty well, movement feels good, combat is quite lethal, you'd better not run into two enemies at once without a potion of each kind, I like that. The game overall looks good, especially the inventory and inventory items. I like the light depending on sanity.
Thick walls which don't take a tile are a bit unusual, I think in general either they're super thin or take a tile, but past the first few second confusion I don't think it bothered me in the end. Too bad there's no winning state, I like a winning state ;) .
The game is cool, thanks for sharing.
