Would like to see a little more in the level. I like that you have different collectables , but I feel there should be more of them to lead the player through the space. Multiple pathways branching and reconnecting is good, but there should be a more to explore and collect. The use of basic shapes to creat little trees is a good stopgap for designing the environment early on, but scale wise it felt like the world was too small and the player was too big.

This is a good start, I like how there are many options for moving around the level and the symmetry of the platforms. There isn't much challenge to the level because it's very easy to skip past the enemies, I would try using the platforms to create a more difficult passage past the enemies. I would also work on using your own designs or finding models for the enemies and items to create a more unique look to the scene.
