Eternal Man: Forest

Eternal Man: Forest is an endless runner about Charles, an ordinary man whose life has become an endless pursuit of perfection. You help him run across randomized platforms and avoid obstacles as his speed increases without limit. Eventually, continuing becomes impossible, mirroring the story’s pursuit of an unattainable ideal.

Charles’s story

Charles once had a simple life and modest goals. Now he is a hollow man whose only goal is to achieve perfection one step at a time, under a society that demands it. Failure is not an option, imperfection is unacceptable, and anything less than perfect is considered flawed.

Running and jumping

You make Charles jump and double jump to avoid rocks, which hurt him. Holding the jump input makes him jump higher. His running speed keeps increasing, with no cap.
