This. Is. So. Sad !
Man, I had thrills when I finished your game ! More than a connection, it's a special boundary you're talking about. It will speak to anyone having kids, and maybe to kids as well (though I would not recommend it to kids due to the story).
Gamewise, the graphics are neat. Did you draw them in advance, or specifically for the jam ? If the latter, congratulations, everything is well drawn and built knowing the time limitation.
I just don't like the sound effects. Personal opinion.
I would have liked to play with a controller, it would have been more comfortable.
Thanks for the touching story.
