These maps require Quoth; at least Drew's map will not work without it (Zwiffle's seems t play the same with or without Quoth on my system). There is, however, no readme in the download and the Quoth requirement is not currently mentioned anywhere on this page.

I'll add the tag "quoth" in a moment and this comment should help, but Spirit or negke, perhaps you want to add it in the map description too?

By the way, they're both very nice speedmaps, and both quite hard.

sm153_drew really does the theme justice with a surreal cross-dimensional journey; very elaborate for a speedmap. There is at least one unmarked secret.

sm153_zwiffle is a tricky and nice-looking coagula-style map.

"Quoth" added in description and listed as a dependency.

I liked Drew's map quite a bit, I was disappointed when it was over. I'd like to try something similar when I finish my current map.

Aside from some tricky platforming Zwffle's map was nice too.

Contract Renewed (sm153_zwiffle) is short -- only 11 kills on Hard -- but sweet. Good atmosphere, some nice trick jumping required, and some suitable unpleasant surprises.
