I really enjoyed the visual aspects of this project. The intro with the title text rotating and the mix of brutalism/non-euclidean geometry in the environments is pure bliss. The lighting in most areas is great as well. The audio, while used sparingly, was also great.
Some feedback to consider: The character movement and platforming feels a little janky. There were a handful of platforms that felt inaccessible, where I ended up using some weird jump physics in specific places to get my way around them. I was not able to complete the first level because one of the platforms felt like it was too far away for the jump distace, and there were no visual or audio cues that indicated I should go explore another area. On both of the other levels, I collected all of the memory fragments, but nothing happened so I used the skip level cheat there as well. I'm not sure if the weird jump physics is intended, but if it is, I think there should be a puzzle early on that focuses in on that, so the player makes the connection when they see spots that use it. I think there's a really great base here that could use a little bit of gameplay updates to make it an overall great game!
Keep up the good work, would love to see a version of this with a little more polish because the aesthetics and story are super.
