A intriguing and quite effective take on the theme!
It's quite rare to see highly personal games, let alone ones made for game jams so I certainly must applaud you for being willing to pour out your life's story for the sake of art!
Conceptually, I think the idea of looking at our ego and our role in the community within different age groups as we grow up to be a pretty compelling one! Our understanding of the individual and the community certainly changes over time. My one critique with the execution of this idea is that your evaluation of your own ideas of the individual and the community is more autobiographical than actually analytical, save for the final scene. That said It's a personal preference more than anything else.
I was surprised by the quality and volume of art you made for the Jam! Making 4 unique characters and 4 backgrounds is no easy feat! Likewise the music was good though it was a tad generic.
An impressive game with a lot to say, well done!
