I really like the atmosphere this is going for. Good music and world. It almost hits the mark, but is held back by a few things:
Moving around the world was difficult. It's hard to know where you can walk and where you can't. Hitting edges makes the character vibrate, which feels off.
Also, I would suggest telling the player how many nuts they're trying to find. Just having a ? leaves me without a clear goal and I'm not sure if I've succeeded or not each time I find a nut.
Polishing these things out this game could be really good!
