Super Time Force

Super Time Force Ultra is an action-packed platformer with a time-travelling twist! You’re in control of time itself, bending and stretching it to your advantage on the battlefield. Rewind time and choose when to jump back into the action, teaming-up with your past selves in a unique single-player co-op experience! Take control of up to 19 unique characters, and battle across 6 different time periods, from the long-ago past to the far-away future.
  Super Time Force’s action-packed game features the unique ability “Time Out”. Time Out lets you stop time and rewind back through what you just did. Then you can jump back into the action with a new character and play alongside your past self in the past, which is now the present. You can use time out to partner up with yourself in the good ol’ days of a few seconds ago, creating a veritable army of you(s).

Dying is part of the strategy in Super Time Force Ultra, so don’t worry about it! When you die, you can just rewind time, add more firepower, and go.
