One word: Awesome! I can't believe that this was built and tested in only 3 months!
First I was (neutrally) suprised about its comic moments but then I found myself in this world. You could have seen me with eyes wide open several times [the train station, the bar and the temple exterior, the battle, the outro!]. So refreshing and nice ideas I never thought of in Unreal! The architecture was decent, and the places were connected fluently, as if one mapper had built them. However, I noticed the difference of the mapper's styles. You took also advantage of 227's effects which added more to the atmosphere (the water in the first cave; great!) but also slowed down the performance at some places.
I enjoyed the story, maybe there were too many twists and side plots, but it kept me playing on. The only letdown were these tiny little messages (as salsaskarrj already mentioned) that can be barely read at once when they are so long. I'd include a custom script which allows you to make the streaming text bigger (perhaps with a different font) and which also grants the opportunity to make a mouse click to read the next message (I know that this is possible: mr hapflinger scripted it for my campaign, as I also trust on messages to carry on the story).
All in all I really loved it and maybe I join the next time for a second volume

I'd be interested in some kind of developer's diary, just like we have written for the anniversary contest. The thread doesn't reveal too much infromation, you know

? Or at least I'd like to know who built which places.
