Love the game so far, the farthest I've gotten so far is layer 4,then dying to hunger caused by sleeping to heal. The only pet peeve of mine is that the crafting recipes reset every run, which makes me disinclined to experiment with complex unknown recipes as my character won't remember them the next run. This leads to me only memorizing a few important recipes like the canteen, rope pack, and dressings.
Also, I love the sound design! The various tracks that play when your character is starving or injured are all great at setting the tone. Even the silence when nothing is going wrong contributes to the unnerving atmosphere.
A controllable slider for durability would be useful, as having backpacks disintegrate while sleeping is not my favorite mechanic.
