Continuum

 The time continuum has been altered! If players can't correct the flow of time within an hour the entire time-continuum will collapse!
 There are five types of alterations spread across the timeline: individual, environmental, governmental, developmental, and cultural. When you fix one it will ripple across the ages as long as there is an unbroken line, but if you fail in your attempt you may make things worse.
 You can play it the safe way, but that takes time, which is the one thing you're ironically running out of, but if you try to go to fast you might make things worse. Make your choices, but get history back on track before time runs out. Oh, and don't create a paradox, or your existence might be erased from the timeline.
  Can you save the continuum before time runs out?!
