I liked the feeling, the art and the atmospheric music. Not sure if I just not found the end of the game, but at some point I had no other choice than to jump down a hole and the game ended. I would recommend to make the hit box of the player (and also some objects) smaller, as it was pretty hard to jump over things and you got stuck even if the character was not touching the object. You also had to run quite a bit over the edge to jump over wholes.
I think there is quite some room for improvement, especially on the movement and hit boxes. Still a good start.
