I'm no mod here or anything, but rather than keep clogging up this forum with calls for help which may or may not be answered, read this first.
As of now there are no written walkthroughs, eg on GameFAQs.com, which sucks, but a lot of people like to see how it's played anyway and there's no better way for that than Youtube. A certain user has been kind enough to give the world a video walkthrough of the entire game [minus the supposed bonus level, though another Youtube promises to upload that in the future], the first part of which can be viewed here.

The other parts should be navigational through the related videos side of the page.
As for the DS version, again nobody has made any walkthrough at all but I'll try my best to find or possibly make one myself.
Robo out.
