Струны времени

This story tells you about an unusual young man. He’s seemingly no different from you or me, but one day, luck simply wasn’t on his side - he ended up in the wrong place at the wrong time. By a twist of fate, the protagonist finds himself in a strange socialist past, where his sole goal and motivation becomes returning home.
But time travel isn’t that simple, and our hero will have to dig deep into the heart of the problem in order to try to save not only himself, but the very thread of time itself.

The protagonist isn’t really a true hero - he can’t just take on everything and everyone. He has weaknesses, and together with him, you’ll have to overcome them.
