I really liked the story (reminded me in some parts of Neil Gaiman's Sandman graphic novels) and I thought it was a creative game with different elements (figuring out if a dream was suitable, and the puzzle part of the levers and matching the settings). Loved the stars moving in the background, and the lighting and special drawings that were made for each dream. The music was nice too.
I didn't run into any bugs, but I did have some feedback: I thought the writing was good, but I did feel like sometimes the conversations ran a bit long. I failed a couple times at first in the lever room but then got the hang of it; I'd suggest having arrows to hint at the directions in which new platforms appeared when you pull the lever, since time is a major constraint. I also thought that the timer for the room investigation was too long, but saw your explanation below regarding not removing it.
Overall, I thought it was a cool and creative game - glad to have tried it! :)
