Before I went back to ignoring my Island I was looking at the sky from the most recent upgrade while it was raining and I got slightly upset due to the lack of water streaks on the glass. With them adding over the years all of the various ways the world makes you believe that it's actually raining or whatever it still feels odd when they still haven't added some things like water droplets or streaks on things that normally have them even when it's still raining. Maybe they'll figure out to add them to things now that they've shown they can give us ok sweat animation.
