Very interesting and ambitious idea! The scope of the level is impressive, and I liked how the visuals changed gradually with the state changes of the character. Also, very creative use of visual shaders and 2d sprites. I liked the little UI guy and his different animations.
With that said, the presentation felt a bit janky to me. Level is huge, but somewhat repetitive, and I rarely felt like the spaces made sense from a practical standpoint, which somewhat diminished the overall believability. I think it would have been better to make the ship smaller, but instead more detailed and polished. Also, text lines disappeared too quickly to me; I wish they would do that only on my input, so I can have some time to read them and ponder on the new information.
With that said, the work you've done is still very impressive! Great job.
