The Raycasting Game Maker is a free easy to use game editor that creates simple raycasting games in the style of Wolf3D. The finished game needs only two files to run, an executable and a pak file with the game data. The game runs in Windowed- or Fullscreen Mode and supports 16 and 32 bit color.
I really like RGM. But there is one main flaw in my opinion. I can't exchange bitmaps like gun pictures and Intro Screens. I would apreaciate some help in this area. I really need to exchange bitmaps, because I have a deadline to finish my game by.
