This was my first, 7-level scenario, and a moderate success. I've been told it's fun to play and has a good storyline, but some of my level design is simple. The Pfhor levels, in particular, aren't really Pfhor-like. Still worth the download.
Construction looks interesting, gameplay is fine, for what I could see... unfortunately, there are too many one-shot doors. Twice I got to a place I couldn't continue because I'd opened a door and not immediately gone through. That's one time too many for me... Four levels, if you can get that far.
8 levels, designed to be played solo (although not together). (These are 8 of the 19 in the Infinity version.) A bit linear at first... but good for a bit of carnage, if that's what you're looking for. No real plot on any of 'em.
Six level solo scenario. Nicely done, with some thought put into how to make you flip switches in a specific order without making it look like you're being made to flip switches in a certain order.
