You have to unpack the box downstairs next to the box with the plant it contains the tv and tv stand and level up the stand

-Clear as many boxes as you can (requires hearts) to unlock stuff you can upgrade.
-Use the radio and TV to watch ads and reset you chats (in order to get hearts).
-Chatting 5 times will give you 1 heart, and some familiarity each time.
-Food will give more familiarity than chatting, but requires hearts.
-Eat enough takeout and the coupons accumulating to the side of the menu will merge into ticket for a free meal.
-Clear red boxes (have to be a certain familiarity level first) to move into new locations.
-Check out every tab along the pages of the store, new items that appear as you level up like the water filter will help you progress (via new options) in the game.

-In the second room will be the TV, and eventually the opportunity to cook own food (cheaper than takeout) and use the water filter (to convert drops, back page of store).
-Before going outside (10 hearts after “bonus” ad), make sure you have saved up your cold and hot water drops. I’d recommend at least 4500 cold/blue drops and 300 hot/pink drops. Check out every free-to-visit location first before spending anything.
-Also when outside, whether park or city, visit the sign-only store (above food truck or the sign poking out of ground next to stores) where you hear a “ding” upon entering, in order to save up enough blue-diamond currency to get a notebook to write in with a pencil.
-You can get the most out of outside visits if you are able to sit and wait long enough to chat (note 5 times = new currency, not hearts) repeatedly and collect items off the ground. If you close the app you return home automatically.

In order to unlock everything you can in the basic store (some options of which you need to upgrade in order to level up familiarity past a certain point - like to level 2 - as well as eventually unlock/be able to move into the other room) is by using hearts to clear out all boxes (even those with items sitting on top of them - like the radio). Make sure to complete the tasks listed in the white silhouette next to the familiarity meter.

To unlock buying options/features, try touching and unlocking all the different boxes you see in the room. The box to the left of the radio unlocks the bed (a very useful feature that allows you to sleep for 6 hours and get lots of droplets). You’ll need to unlock the box UNDER the radio to level up early on.
