Roguelike game idea

Roguelike where whenever you die you reverse back one step in evolution and gain and lose abilities depending on what you become. After you die as a single celled ocean organism, you have to restart the game. For each level you make it forward, you get to advance the evolution/history of your character (start as 21st century man, make it through and be 22nd century man, etc). But if you die, your character regresses in time (back to 20th century man, then 19th, etc). Die enough and you start becoming a caveman, then earlier hominids, eventually a little rodent mammal from dinosaur age, a tikalik, and so on. And then you restart the level as a less evolved being and have to beat it. Game files - once started - can't roll back to prior save states. By going through the levels, you discover that you've been kidnapped by aliens, who are controlling what you're doing. It's EVILution.
