Time Drifter

Drift your way through time to save humanity from an evil panda

Scientists have made a mistake... The panda they were experimenting on has become a monster. An all-seeing demi-god with only revenge and destruction on its mind. Only the research facility's janitor can be sent to the past to save humanity. Unfortunately for him, they send him to far. Drift your way through humanity's history and fight everything that's on your way. You're the janitor after all. You've got to clean things up.
