What code does the seller require?
From the walkthrough:
"Version 0.2.4-dev
1. After the main character was at the club and completed the "Dog Games" scene (where he pets her in the hall, and they play dog during the day), the opportunity to progress further appears.
2. In sandbox mode. To do this, you need to be at home and look at the phone icon (it vibrates), you need to answer the call and eventually go to Johnson.
3. You won't be able to get there, because as soon as you arrive, you'll accidentally be met on the street by a guard from the club. Here are several options:
a. Go with him to the bar and talk him into it
b. Start a fight, win, search him
c. Start a fight, win, go with him to the bar and talk him into it
In all variants, we eventually get information that at the store, using the code word "Laocoon," they will give us a mask. We go to the store and get it."
