I think that you have a really nice proof of concepte here and I like the art style, but I also think that the game lack replayability and player guidance. I just hoped in game and placed some traps without really understanding what I was doing and just got a couple a fur after resting. And that's great but I don't really understand how I could do better next game.
So I think that the first thing that could be improved is replayability. Otherwise I think it's quit fine !
