Thanks for your feedback. Very useful.
I suppose the biggest use of this feature would be for 2 friends to play together without limit, with only one needing Magic Potion.
After all, if you have Magic Potion, make friends with someone and want to play with this person again, it is a bit unfair for you to have to wait for their food, isn't it?
Please keep your thoughts coming as we are still undecided on this one.
