Hi, i'm really enjoying this game! The rubber stamp doesn't seem to work for me though, even after refreshing the page. i can move it and i get the outline when i hold it over a package, it just doesn't stamp. (firefox on mac) Hope this helps!
Thanks! Hopefully that's just our bad for not explaining the controls -- you gotta left right-click/press "R" while holding it over the package. If that doesn't work let us know! But very good point, we should definitely explain that in the game regardless
