Stamina
Stamina is one of the most important resources that players must manage in Coral Island. It is used to perform various actions such as tilling, chopping, watering, fishing, bug-catching, and cooking. Each action requires a certain amount of stamina, and if a player runs out of stamina, their movement speed will decrease. If a player overworks themselves and completely depletes their stamina, they will pass out and will be taken to the clinic and charged for treatment. It is essential to keep an eye on the stamina bar, to avoid passing out and incurring expenses at the clinic. Player can also recover stamina by soaking in the Hot Sping, once they have unlocked it.
In addition to stamina, players in Coral Island also have to manage their Health points (HP). HP can be depleted if the player is attacked by enemies or if they consume unhealthy food. It is important to keep an eye on the player's HP bar and make sure it does not reach zero. In the mine, if the player's HP is depleted, they will be brought back to the entrance of the mine. It is essential to take care of the player's health by eating nutritious food and avoiding taking damage as much as possible.

By giving 2 temple offerings, the goddess will recover hotspring for player. however, since her power is still too weak, the hotspring will only heals 1% Stamina/second. As player gives more offerings, the Goddess will get stronger and hotspring will recover more and more stamina each second.
