Бесконечное Лето 2

Everlasting Summer 2 is an interactive visual novel about Alexey, a young man from the 21st century who falls asleep on a bus and wakes up in the Soviet-era summer camp “Sovyonok.” But the camp has changed: secrets are more plentiful, relationships more complicated, and few people Alexey meets behave the way he expects.

Alexey is swept into a whirlpool of new acquaintances, mysteries, and strange events. Not only must he find love, but also figure out what happened to the camp, why it has become different, and learn what it means for everyone involved.
