I like the idea and simple premise but I wish that at the start of the game you are given a base from where to start from. Meaning like there's already a friend in the group and you are building upon that group. Better yet, let me build my own profile where I get some simple "likes, dislikes" options and then let me choose the friends from there. Doing so I think would make the game even more fun. interesting, and engaging plus if you could "kick" a friend out of a group that would be good too but like the damage is already done so the person leaves but your happiness percentage remains the same until you replace that friend with one that is more in-tune with the group. Just some top-of-my head ideas. Nice work :D
