This is a PSP port of an unusual roguelike Save Scummer by Jeff Lait.
The only action you can perform in the game is moving through the time forwards and backwards; the character moves, attacks and collects weapons and potions automatically. Remember that after rewinding, then progressing the time you may not end up in the same state! Watch the monsters miss every strike or cycle until the monsters are in perfect position to cast a thunderstorm on them.
