This game was really interesting to play, sleeping was a bit boring though. At the beginning it was fun to experiment and combine items, but when you get more items it's getting more and more tiresome to find the right combination. I was almost done with raft ( I think :) ) but I didn't finish it, 'cause I got confused in all the items I had.
I think you could have made something like a dialogue bar and when crafting a new item character can tell the player what that item can be used for.
Mostly had much fun playing it. Great job.
