Exploration on the clock 

The main feature of Outer Wilds game is the time loop system incorporated in the gameplay. The player's mission is the time constantly resetting, as the system's star goes supernova and consumes all nearby planets.

The player's job is to explore each world and gather enough clues to continue their mission before the time-loop closes again and the astronaut is returned to the starting point of their mission. The player retains all knowledge of what happened in the previous loop – for example, finding a hidden message leading to a clue carries over, so the player can go straight for their objective and ignore looking for the message again. 

While exploring the alien worlds, the player will have to keep an eye on their health and oxygen levels. They can be replenished y locating a world with trees or returning to the ship to resupply. Dying before the loop ends returns the player to the start of the game
