Schwatz!

Plot

A new cool chat client  is out. It connects via the dark web anonymously with random people worldwide and leaves no digital traces (at least it is said so). And it's completely free.

At first, everything looks as usual, but the longer you use this chat client, the more strange your conversation partners behave. What's behind all this? It's up to you to find out.
