Cool concept, cool execution. I liked the (shader?) effect that transitioned between the 2 structures, too. I feel like you should have utilized the concept more because it was very enjoyable to use (you used it a lot at the end but I think some more spread out use of it would be nice). Only issue I had was the camera, I couldn't control sensitivity and the sensitivity was really high, which made the game kind of hard to play, especially it being a 1st person platformer. The camera also seemed to accelerate and decelerate which just makes the camera way harder to control. It would have been nice to have more deliberate movement there. Very nice game though.
