I'm gonna be the dumb guy and just admit I didn't get it
Loved the visuals and sound. With so much pixelation and dithering, environments stop looking like video game assets and remind me more of 90s pre-rendered CGI. And with such limited clarity, the great sound design really shines because it becomes your main tool of perception.
That being said, the gameplay is basically just go forward and occasional jump or left-click when the game tells you to. The walking speed is so slow that it actively discouraged me from exploring because it takes forever to just walk to the other end of the room.
Still I was curious enough to see where the game is leading me. Not fascinated, not dying to know, just curious. Then I got stuck. It was in the caves, where you use projectors to scare away the shoggoths and clear a path for yourself, and find that sphere. Couldn't interact with the sphere or go anywhere other than back because I was surrounded by the shoggoths. I tried going back, but the door was closed. Seeing how the only mechanic in the game is walking forward and clicking on things, I seem to have exhausted all my options and gave up.
