Zanam, by original creator you mean Shigeru Miyamoto? ;) Awesome idea, but Capcom, Nintendo and Konami might be interested in this, or their lawyers...
Oh, Tasselfoot's walkthrough depends quite a lot on timing and forces his way through some levels. But there is a slow solution to almost every level that doesn't require timing / fast reactions.
hollygrove, Thanks for the bug report! I had forgotten to reset the achievements bits when you press "reset progress". Now it's fixed, but you need to reset your progress again...
Thanks guys, and sorry about the walkthrough! I'm the first one I ever made, and I was asked by the sponsor to do it myself personally. Well, at least it shows some kind of a solution to every level. Took me around six hours to record...
