I love the music and art. Consider adding sound effects to a few actions/events, or all of them. Sound effects really add to a game, no matter what kind of sound they are.
Also, it could just be me, but I didn't find a chest at all in the first level, and the second level just had me start with a knife. Another thing to mention is that it felt a little misleading how you couldn't climb up ladders.
I'm curious to see where this game goes, I think it'll definitely feel better with a little more polishing, keep at it!
