Played this early in the jam and retried again for rating. From the outside it's a rather simple idea, but it's very well implemented and visually and acoustically appealing - even with multiplayer and a simple, but sufficient intro. When I played this the first time, it wasn't just a relaxing experience: I saw someone else and all I could do and all they could do was to wave, and so we did. This short encounter added another layer, a short moment of joy and kindness, which are so dearly needed nowadays. I don't see why this entry doesn't deserve full score on all categories.
