Helle everyone. I've never played this game, but today (February 12th, 2025) I just got this achievement (see the photo) . Has anyone also received this achievement?

как? это одиночная игра?

Я провалился под текстуры на локации с днём рождения

I never played any backroom game. What is the goal ? I understood it's an endless basement but I can't find what to do. I see the differents objects (tape, screwdriver, rope, ...) and the wall text saying "Can you see it" ... but what else ? Is there somewhere to go or something to do to go on ? ^^...

They said "lots of levels" but I wanna know the exact number of levels and what they are. 10 levels? 50 levels? 100 levels?
