This movie was the first thing UY I ever watched years ago, it also made a big impression on me. I think it's not surprising considering it was directed by Mamoru Oshii who is a big shot in animation (and live action for that matter). Years later, because of that movie I've watched countless of hours of Urusei Yatsura media.
There's no anime recommandation that comes to my mind right now, but if you like live action I'd recommend Lonely Heart by Nobuhiko Obayashi, it has a similar magical/melancholic bubbly high school atmosphere and it's very beautiful.
Also want to share my favorite scene from Urusei Yatsura, I find the song to be very calming :
