Energy determines how long the player may remain active during the day and is displayed as white bars which can be found in the top left part of the interface.
Energy is shown by six, white, rectangular bars located on the top left part of the screen. These bars will decrease when the player is doing activities such as Fishing, chopping wood, walking a certain distance, etc. The player's screen will gradually darken as the player loses energy. If the player's energy bar reaches zero, the character will fall asleep and wake up at their base camp.
