It's starting to look like something. I only need to iron out the really weird corner effect, but that shouldn't require a ton of math work to fix up. (:

After that I'm going to start working on making nice-looking walls rather than sprite-y barriers.
Looking good, good job.
Looks like you fixed the major issues. I think the only thing needed to fix now is the positions (it looks like a fish eye lens with the current math).

Nevertheless, this is awesome!
Doom style lol
Reminds me of AFterburner II
