This was intended for kids; I remember it being a group of really young persons. I remember stuff but not enough to explain in detail.
I think there was some kind of orbs on their ship, and like I said, this must have been meant for young kids. I don't think it was done in manga style movie ,nor did it have any scary monsters as far as I remember. I've been trying to find this for a while, but with not much content to go on it’s really hard to find.
I must have seen it around 1984–85 ,but it probably wasn't brand new. I saw it on Swedish television or a rented VHS tape. It was a upbeat movie.
