Hinkman

Hinkman is a turn-based RPG in which an angry, old man gets constructively criticized once, which makes him travel through time in order to prevent the critic from being born. After being insulted, he assaults the critic, and is sent to the city of Sideway (it is never clarified how this happened; this will most likely never be resolved.) He meets Grass Albert Einstein (you can guess what he's like from the name,) who invented a time machine. The machine malfunctions while Hinkman uses it, and he is sent to random time periods, and must get back to the present/past/future.
