The Internet has long become an integral part of modern man's life, and the issue of personal safety online is only becoming more relevant. Most users do not care about their safety on the Internet, because they simply do not know how to do it properly.

Each game is a different story in a fictional world. This world is visually different from the real one, but contains direct references to the problems of the present.
