One day Sisyphus got mad. I mean really angry. He was so ♥♥♥♥♥♥ off he ripped through time and used his boulder to break into the house of and assasinate over 20 of the most historically significant people of all time. This is like the opposite of Time Squad.
I was going to dismiss it as shovelware early on but it was suprisingly challenging and varied, though not so long that it overstayed its welcome. This is how you make a casual game.
