General

The game and atmosphere can really hit home with some players as the music and gameplay really captures the nostalgia and feeling of moving, especially to those that have had similar experiences.

Stage 4

When the protagonist moves into her boyfriend's apartment, there are already signs that things are not well in the relationship. He won't rearrange his own items to make room for the protagonist's, meaning she has to struggle to find places for her personal possessions. Most upsettingly, her diploma must be tucked under the bed or shoved into the closet because the boyfriend won't remove his posters to make room for her.
While the protagonist can put her stuffed pig on the bed, it clearly looks out of place on the grey sheets - clearly a metaphor for the protagonist herself.

This stage in general; the protagonist moving back into her parents' house shows that she's fallen on hard times after her break-up.
One small detail gives away that protagonist's break-up with her ex-boyfriend was a very unhappy one. If the player tries to put up a picture of the two of them on the corkboard then the pushpin is put right through his face. It cannot be left on the corkboard, either, as the game will only let the player finish the stage if the photo is tucked away into the cabinet.
The music for this stage is quite sad as well, and even the song on the radio, which has previously always been upbeat, is quite subdued.
Certain objects, like a pink cup with a heart on it and the stuffed pig from the title screen, get damaged and worn down at certain points. Fittingly, this happens when the protagonist is at her lowest point.
Some of the items the protagonist needs to unpack are heat pads and pain medications, showing that she is suffering from long-term health problems. How she developed these problems is left to the imagination.
Aside from the wall, one of the valid places for the protagonist's degree is under the bed, which can make it seem like the protagonist is so broken after the episode with her boyfriend she's stopped caring about it at all.

The protagonist still has painkiller medication, but now also has a walking stick. Despite having her own home again and plenty of room for her own items, she has not yet fully recovered.

The song during the credits can bring Tears of Joy after seeing the protagonist find true love and finishing moving.
