Hello and welcome. I recognize the name...didn't you do a Duck Tales map? I honestly didn't look, if I'm right, I don't know why I remembered that.
Man, the Dizzy games are hard. I had a brief Dizzy phase a while back on the old forums after seeing them available on Abandonia (I think they still are there, for those of you who are interested, until Codebreakers or whoever it is brings up a beef with them). But I never got very far, though I probably got farthest in the PC version of this one. I guess you're adamant about doing the NES one over any other version. The parallax in the PC version is a pain anyway, and if I recall correctly, someone (maybe Terra or Grizzly, I think) posted a link to the PC version's maps on a foreign language web site.
I'd like labelled maps, though I suppose making an aesthetic map without labels comes first anyway, so you might as well keep an unlabelled version for those who don't want any text on 'em.
Because the Dizzy games are those that aren't easy at all, and it's not clear where to use items, I encourage on-map labels. Though as with anything else they should be neat and concise. If people came to VGMaps.com for strategies, they'd come more often.
