Just played this. Such a cool idea to try and port levels from X-Treme over! I've been having trouble getting the fisheye and camera to work, but the level was fun regardless and this in general is just a cool idea.
Have you made any progress on the project as of late? I'd love to see more stuff from you.
EDIT: So I tried activating the X-Treme camera and currently my character models have reverted to 2D, the screen-size has shrunk, and my controls have been remapped. I think I can just map them again myself, but I don't know how to fix the other 2 issues. I already deleted the files related to fisheye and the camera and such to no avail.
Nvm, was able to fix everything!
