Sujet : Too short?

Ok, I wouldn't know if it was short because a long time ago my SM got corrupted and I can't remember any levels about it except the ones i've already played. One question. Is Otto the final boss? i've gotten to Otto on planet Quodrona and I really think its the end. If it is or isn't someone please tell me and I will either agree or disagree with this post. Thank you…

i think it was puposely made short. the game i think was meant to be a cute little intermission game for after UYA but before DL and the future games.

The game could've been longer but it was still fantastic anyways emoji.
