itch.io

go in the office -> press the biggest monitor on the desk -> Open PC -> shop -> Items -> Metal Bat.
if you don't have enough money, press the Money button on the  pc interface a few times, if it isn't enough yet, end the shift and re-do until you have enough money to buy it.
to collect it, go outside the pizzeria and you should collect it.

tell me if that works! I hope that you have a nice time playing!
