SOLID WORK!
In your devlog you mention trying to create an atmospheric game, well good job on that.
I like how the little consoles show the current color of the wall so that even if wall if out of view you can know.
Also the splitter mechanic introduces good gameplay.
The camera controller could be a teensy bit better tho as it was nauseating at times, as well as the box grabbing mechanic it sometimes didn't register and had to go and grab box again.
p.s. In your devlog you talk about mesh colliders, they should generally never be used in games as they are too performance intensive, most gameobjects can be approximated using a set of primitive colliders. Like in FPS shooter games the player hit box is not a mesh collider rather a set of mostly capsule colliders fit into each body part.
