No but I saw in a video that it was touching another box which causes a fail. A small visual or audio input would do the trick. One can imagine that the customer shouts when it happens "Oh no, but you are completely stupid or what"? The frequentation of the stores is different according to the hours, is it taken into account?
I am delighted to have entertained you. Thank you for ping, it's rather funny to note that some don't spot the ironic digression. So it will be really funny to know that people will read so far to realize that they have been fooled. The sound/music and the art are awesome, i hope you're already enjoying a new gamedev.
