I think its funnier that Bob is on the chubbier side, love the irony. Also if you could have customers complain when Bob pushes them and customers showing gratitude when he fills up an empty shelve the customer is looking at, that would add a layer of personality as well. Currently customers feel very 2d even though its a 3d game. Hope that makes sense , I have followed you so I will play the updated version as well. Keep it up bro :D
