Well, this is what screenshots promise. Always good to see a game that despite simplistic gameplay manages to take you some places just by using the atmosphere.
If I go into interpreting too much, that "trash" reminds me of typical friends that might end up hanging in your house - a wannabe criminal, a junky, and the jar is maybe a smartass who feels superior. But grandma says you have no friends in there, so assuming that is true maybe these are the main character's potential personas that he is trying to get rid of and the phone is super-ego and blah blah idk but it was fun.
