Well, I generally try not to repost what others have said, but... [expletive], this game looks great! Also, I was creating a scifi game like yours (inspired by Doom 3... sorta), and I was wondering, you mentioned that you had a buzzing noise like fluorescent lights make, right? Can I have it and give you credit in my game?
One more thing; I have a budget of... $0 for games right now, so, my 2 cents on the price is I'd much rather it be free (n00bs like me like free stuff).
Another last item: I like the "Chapter" system you thought up; may I use it on my (freeware) game, with more credit given? (I don't know about all these intellectual property copyright things, but I'm sure as heck not getting in trouble with them.) Hey, my download is done! I hope thse levels don't take to long to load - I've already waited 6 whole minutes for it to download.
Changing the connotation of "noob," one post at a time.
