Thanks for the feedback!
I strongly agree on there not being a lot of difference between the awake and sleeping modes. I had an idea of you being placed a bit away from the body, and having a enemy spawn on the normal body to guard it from you to make recovery a bit harder, but there should probably be more to it still (like more types of enemies maybe).
An idea I had to up the difficulty was to have barriers that required you to kill all enemies to progress, but I didn't have time to implement it, nor was I sure that it was the right option. But it would hinder the player from just running to the end, as I did during testing.
And thanks again for the comment. It's really appreciated <3
