Ideas for a Game About Loneliness

[Clamfish]

I'm in a game contest, and I chose to make a game themed on Loneliness! However... I uh, have no plans? So please give me some ideas for it! (you will be credited in the game!)
Here are some ideas I have:
- You are a black cat and have to avoid and hide every day
- You are something that did something horrible and now everybodys scared of you

but yeah please help me ;-;
