game.set_up()

I would like for you to try this script. It works perfect!

Master I like your game it is very fun.

I have edit the code because it didn't work for me in the beginning I changed:

space = eval(input("Pick a space: "))

For this: space = int(input("Pick a space: "))

Hope helps other too
