Becoming again?

when Jim uses the chronosphere to rewind time, things don't exactly go as planned. Jim is now tasked to save his friends and family from the evils the lurk in the shadows while gaining new allies along the way.

Basically, Jim travells back in time to prevent the future but things get a little out of hand.
