This was a really cool concept! Sadly, I have no friends 😥 so only tried it singleplayer, but still was fun!
Packing mechanics, etc work well. I did have trouble moving the weights whatsoever sometimes (couldn't pull from shelves) but usually after a few minutes I could eventually pull one off. I didn't quite know whether my packages were being sent properly? Was tapping the tablet supposed to do anything? If not some kinda visual/audio signal would probably be quite good there!
I'm not sure whether I actually successfully shipping anything, but I had a fun time trying! thanks for submitting!
