Time rewinding in zeit² is not simply a way to undo things but an essential feature to beat the game. When initiating time travel, rewinding will continue until you either release the button or you run out of time-travel-energy. During that period your player and everything else on the screen is being rewound. As soon as you stop traveling back in time, the game starts playing forward and you are in control of the player again. While you are in the past there will be a ghost or shadow of your player that plays exactly like you did before. You are on the screen twice, as the normal player and a black version of it. Go back in time at the right moments to get the advantage over your enemies by having the doubled firepower that time traveling gives you. The time-travel-future mechanic lets you speed up the game at any time. While you are in time-travel-future all the points you score are doubled. This feature serves to improve score and pace the game when it feels slow for advanced players.

Different ways of interactions with your time shadow combined with your multi-level chargeable weapon give you an arsenal of tactics to fight your enemies. The additional weapon systems include a chain shot that jumps from enemy to enemy when fired, and a blast shot destroying everything on its path of impact. zeit² is based on an energy balancing mechanism rather than discrete lives. Every enemy passing you drains life energy from you, and enemies you shoot give you energy back. The dynamics of this allow you to experience a continuing flow of game play. You can feel the excitement of regaining energy after a situation that seemed like a dead end at first. You constantly decide between risky scoring moves and life saving actions.
