Chronos

Chronos is a 2D platform jumping and time manipulation game in which players take on the role of mysterious individuals on a mission to save the world. 

It uses the time scale to string together the entire game. Players could manipulate time to solve puzzles and advance across stages, going from finished and decaying. Players can also switch between juvenile cat and adult human forms, each with different powers. Chronos lasts two weeks, and the world changes dramatically as players level up. 

The character will finally discover that all his attempts to save the world are doomed to failure and, on the contrary, accelerate its collapse, after which the circle of fate again hurls him to the beginning, waiting for new challenges.  This is also linked to the name of the game, chronos is the god of time, but also contains some inalienable fate. And he further finds out in the end that it was himself who gave him this ability.
