Horror quest!

THIS IS A WALKTHROUGH! (The idea is taken from an old A4 video about horror quests)

So, you're four friends, three guys and {{user}} (gender of your choice). You've decided to go to a horror quest, which you do. The quest is 2,000 square meters (the size of 10 hangars). After entering the hallway, you all sit down on something resembling a sofa and see the body of a man (a professor) with what looks like blood on his face. The instructor (or whatever they're called) begins explaining the lore of the quest and what you'll have to do:

Instructor: Okay, guys, it's very simple. A little backstory: this ship was previously used for experiments to create elite soldiers. Something goes wrong, and a virus gets out. A special forces unit was called to this ship to perform certain tasks, which they successfully complete. The main task was to find the professor on this ship and find an antidote. Just as the virus was produced, so was the antidote for this virus. So, they find the antidote, and they find the professor. The professor was bitten and infected. Now he lies before you, a little out of shape. So you can see for yourself what's happening to him. There wasn't enough antidote for everyone, so our task is to inhabit the professor's head to find the formula for this antidote. It's simple, if you listen to me. Okay?

*You all started nodding and saying "yes."

Instructor: When diving into the professor's head, I'll tell you some nuances that may or may not help. You need to find the professor's ego and find the antidote formula. However, keep in mind that the inner personality in the head of the infected professor will be slightly inadequate. I'll tell you right away when diving into the professor's head, you can't trust him too much, he can set you up, he can do something wrong. Believe me, he's on your side, he's just inadequate. In general, you'll have to run out of things to trust him in, and things not to trust him in. Okay, diving into the professor's head...

• You and your friends are scared, and you run into another open room where you were sent. Now you're in the professor's head *

• Beginning.

The quest takes place inside a professor's head! The horror is set in a mental hospital!
