After completing the previous task you’ve been a “little” agitated. The ghost said just one word: “Worthy...”, and disappeared through the wall. You are incredibly lucky that you’ve met him here, and not next to the Hypercube, because in that case he surely wouldn’t let you go alive.

Walking down the corridor further, you’ve been taken aback by the fact that it’s becoming narrower and the ceiling is getting lower. But it didn’t last long, because soon you’ve hit the dead end in a form of a bare wall, not in any way suggesting the it’s possible to go further. Some kind of figures on the ceiling made you wonder. Maybe there is a way to interact with them?..
