The character does not have health points, only an oxygen scale.
The character's death occurs as a result of the end of time in the Oxygen mask.
Upon completion of the Oxygen mask timer, the player is moved to a safe place.
Monsters, instead of dealing damage, deduct the remaining time on the Oxygen mask.
All items collected in the mine disappear from the player's inventory.
A bag with all his collected items remains at the player's death location.
If the player comes to the place of his death after respawning and picks up the bag - he will return all items to his inventory.
The bag is not saved after the mine is updated.
