An incredibly cute game!
And the most amazing thing is how the mechanics convey sensations. That's what games are supposed to do, and you've done it beautifully. I truly experienced the transition from familiarity to a more intimate connection. In just 5 minutes. Movies can do a lot, but only games can create that kind of experience. And that's wonderful.
Naturally, it's a great alternative to Florence. And recently, my friend made Love Letters - https://nozomu57.itch.io/love-letters.
I think the music and sounds will make your game even better.
