Unknown VHS sci-fi western-style cartoon movie from the 80s/90s

Question

I am trying to find a Sci fi cartoon I watched when I was younger but cant remember what its called.

• It had a young blond boy alone on an alien planet
• he grows quick and uses an old space ship he finds on the planet to travel space
• while in space it becomes sort of like a surreal journey. Meaning I remember the ship being pulled apart and put back together
• he finds two people at the end who I believe where his parents but I remember its like they don't know or remember him
• it was a VHS cartoon movie from the mid 80s to 90s. It's animation was western style ie sort of like Scooby doo
• The Phantom Tollbooth is too Disney styled animation.
• it pretty much just focused on the main character the whole time.
• I'm sure that no one actually spoke during the film.

Answer 1

Les Maîtres du temps aka Time Masters from 1982.

The film centres on a boy, Piel, who is stranded on Perdide, a desert planet where giant killer hornets live. He awaits rescue by the space pilot Jaffar, the exiled prince Matton, his sister Belle and Jaffar's old friend Silbad who are trying to reach Perdide and save Piel before it is too late.
