Very impressive!! I loved the use of a serious text-to-speech for the start, it fit very well. The platforming felt good, and the little stories that could be observed added a nice touch! Can imagine you could make a very emotional full game out of this! I'm impressed by how whole this felt, the art was great throughout, also impressive cutscene art! And you even have credits!! Well done.
Some small feedback since it was asked for: I'd make the music sync up in the background, and just switch tracks when you switch eyes, so it doesn't start over every time you close your eyes. I also felt the transition could start a bit faster, I didn't mind that it wasn't instant but it's nice to get quick feedback.
