me and my significant other really enjoy this game. only thing that's bugging me is the pebble system. you can only get them through daily logins and limited ads. would love it if we could have other ways to get more pebbles since the interiors (especially limited ones) are really expensive! but besides that the game is cute and would recommend it to other couples :>

A very cute thing to try out with your partner. Doesn't take much time to answer the questions, so it's very convenient to keep at it and the customisation is very cute although very tedious to get without using irl money, but its free and I see that this has to be for them to keep the app running, so it's still a 5 star for me

this program is a very cool way to keep a couple close and be mindful of each other. interface is a bit difficult due to the in app sales tactics. be easier if the sales/ donations is easier and streamlined. overall, I like the program to keep us connected. just hard to navigate.
