This was kinda wholesome. Based on your game description, the story and the stuff you do in the game all make sense together. In my opinion, it is a nice game, but I can give you some suggestions to make it better :D
It would have been perfect if you had more animations in your game. During my playtime, the couple were just dancing, for instance, you could make them sit on the sofa or do something else.
The music in the game is good but not looped perfectly.
If you had other environments as well, that would have been perfect.
It is a nice game and can be improved a lot. The concept of rewinding past memories ties in well with the theme of "loop." Well done! :3
