Wassup!
The game is really good in terms of environment design, but it really lacks in a structure and some kind of gameplay flow. I think it would be nice to add some really kind of dangers like a bear or smth. Also the game would feel more engaging with a third person view.
Anyways, I think you are a great level artist at your level and I would really like to help you to build a better gameplay for your gorgeous levels)
Great game ;)
