Gameplay-wise I would probably want the game to have something more, but... I believe for a game jam game, your focus was in right place. The game is beautiful and I am not talking only about the visuals. The metaphor of the knit jar becoming more full as we go through our memories is a nice touch and the game with its nostalgia focus and the "feels" hits very close to my heart.
As a game, I would want more gameplay. As an experience, thank you.
