Posting this quite late. Finally finished brushing up the second part of Claustrophobia as an independent release. I must say, I'm much happier with the result: "Autophobia". It represents my commitment to pull through on these projects and finish off what I start. I took advantage of having to rebuild the level from almost the ground up to experiment with custom music, textures, and particle effects. Some things worked well (blue anti-portal walls to break up monotony, ambient piano music, bridge of light) and some things did not (new anti-portal floor texture, steel wall texture), which has taught me more about my talents, and the fundamentals of good level design. Never try to mess with previous player training. It doesn't matter if it makes logical sense to you, in a player's mind, everything is shapes and colour. Even the slightest discrepancy can be confusing and frustrating.
So without further ado, I present a link:
Now I should probably get to finishing optimizing zpo_shaun_v2. However, after all the time I've spent with it, I can hardly bear to look at it in Hammer. I'll get it done eventually. :P
With the conclusion of zpo_shaun_v2, all outstanding projects of mine will be completed. That means its time to start something new. I'm excited about going back to some solid design work. The next step is either another "short-and-sweet" Portal map, or launching into a full-fledged single-player HL2 mod.
