Gameplay
The player attempts to get the key to the correct chest within the time limit. If the player gets the key in the wrong chest, he or she should move on to the next one and try again. However, if the player does get the right chest, they grab a new key and to keep going. If there's time left, then the player should go back to the ones that are locked.
