For now the customers do nothing but walk around in the pizzeria and leave.
Here are some suggestions that could improve the immersion:
-Sitting down and eating
Make them be able to sit down on pizzeria chairs and even eat some pizza
-Interacting with the pizzeria
Things like using the vending machine, looking at the animatronics,
picking up and wearing party hats,
playing the arcades,
and maybe avoiding stepping on the stage or just not going places they shouldn't be in
Perhaps the kids would have a chance to go to these places because they're stupid
-Kids playing
Perhaps just running around the pizzeria and following eachother idunno what elese they would do.
-And of course probably the most requested being earning money from them visiting your pizzeria, perhaps like 5 fazbucks per customer, 10 or 15 if you get lucky and scam a person or two.
Thank you for reading my nonsense ramblings.
