Clannad spoiler (don't read if you haven't finished clannad after story)
Essentially yes, because he collected all the stars (wish things) for doing good things, he got that last wish which turned back time to where Nagisa didn't die and Ushio is still healthy. I don't fully understand the robot story but it goes along with the story in some magical way.
Why didn't you mention the newest Key VN adaptation? Little Busters is a more lighthearted variant of the themes that are in Clannad and Kanon, but seriously, at some points, THE TEARS WON'T FUCKING STOP MAN.
i download it for now...can't wait to watch it
