This is a visual novel that is a bit more complex than appears on one playthrough.
You play as a young person in a relatively small town or suburb whose friend is leaving. You're part of a friend group with girls (I believe, from the art) named Clover and Iris. You have a thing for Clover, and Iris is beginning to notice. But Clover is moving away.
The game mixes weather and feelings into a metaphor with the snow kind of being like the relationship.
There are several dreams as well.
Overall there is a melancholic goodbye feel. It reminded me of several similar situations I had when I was young and didn't have control over my location, or when I did have control but it meant saying goodbye to people.
There are multiple endings that depend on your choices throughout the whole game, I think 5 or 6 total.
