I actually proposed a game very similarly to this using a bat and echo-location. But I feel like your lidar system worked a lot better than my visions. The minimalist design worked really well. The sounds, the colour coding, and the some what directed objectives really came together. my only desire was a bit more character animation and maybe more discoveries to be made while approaching things in the dark. But for fumbling in the dark, Ive seen games do way worse. Got to the ending too
