I'll edit this review when I am able to do a thorough trial of this.
For now — and at the risk of abusing a review: The textures are done well. I would recommend to the author either that they develop a scenario which makes good use of these aesthetics, from this and from Frolic, or that they release all their textures alone for others to build upon.
Review of the mapmaking is forthcoming.
This is a little map-pack I made to show what I'm capable of doing. It's not masterpieces but I'm pretty proud of my work.
It contains 4 maps and a shapes file which replaces the Sewage set. The maps are:
Horrible Horrid Environment And Demise (Negative at first yes)
Just keep yourself wise with the rating. This is a beginner's set.
EDIT: I forgot to add that this requires a certain song to be better. https://www.youtube.com/watch?v=tCYhXCkcbas
