Wow, you've got a whole level here! It's great to see some design work on these short term projects. A lot of the time, I'm always focused on mechanics and I never get a chance to do any level design.
I can see here that the platforming and camera implementation are flaky, and time was spent on the art and design of the experience. There's a natural progression to the level design and I can see what you were shooting for. The diversity of the enemies also add some texture to the experience.
I think what you have here is really good given the constraints. I'd encourage you to continue honing your implementation skills, and find new opportunities to flex your design muscle. If you can keep that up, I think you have great potential to be a game designer.
