I played it for about 20 minutes and couldn't make any real progress. and that's a shame because this seems like the kind of game I've wanted for a long time. Maybe I'm missing something but it seems like it would take forever to get enough resources to make the most basic healing item, so if you die once you're pretty much screwed because you're stuck at 50 health. there should be an easier way to get healing items, maybe a similar system to the estus flasks in dark souls with potions that refill every time you go back to your tent.
roguelikes hold the player's interest by giving the player random loot. I didn't feel as motivated to continue once I found the 1 chest in the level. It seems like it would be easy to make a bunch of items that just improve stats by small increments. their effects would compound and give the player a good sense of progression. But I bet that you already plan on doing something like this.
I'm eager to see where you go from here, this has a lot of potential.
