Question

put in mind that your enemy is in the island to and looking for the treasure Where do want to go? 1-Through the jungle 2-To Around the island please choose (1/2)1 Do you want to play again please choose(y/n)

Answer 1

This happens because of this part:

    try:
        location_old = int(input("Where do want to go?\n1-Through the jungle\n2-To Around the island\nplease\
            choose (1/2)"))
    except Exception:
        pass
    while location_old != 1 and location_old != 2:
        # Game continues

If you enter 1 or 2, then the loop will not be entered, so your method just returns and the game ends.

If you enter an invalid value, such as 3, then the loop will be entered. You'll then be re-prompted for your answer, and it'll work better from there.

A quick hack would be to simply do location_old=-1 first instead of asking the user.

A better solution would be to write a method that asks you a question and re-prompts until you give a valid reply. That way you don't have to add loops everywhere, making the code easier to write (and read).
