Please test and comment my raycasting engine! You can download it here. Here are some screenshots: 
This is a raycasting engine like Wolfenstein 3D has, but pushed to the max! It supports: -animated sprites -floor and ceiling textures -teleporters (moving items like projectiles will go through teleporters too) -thin walls (Wolf3D only supports blocks) -45 degree walls (Wolf3D only supports 90 degree walls) -round walls (not at all in Wolf3D) -a lot of different weapons (try pressing keys 0-9 several times) -paralax backdrop (sky) -explosive barrels -flashing light effects -waving lava that hurts -no AI and enemies YET -secret push walls like in Wolf3D -decals (sprite textures that you can put over walls, floors and ceilings) -24-bit colors -128x128 textures -you can put sprites in corners and on sides of tiles too (in Wolf3D you could only put them in the center) -weapon projectiles that bounce against walls (weapon 7) -the map is read from a png file (I was too lazy to build a map editor, why would I if you can edit the pixels of the map with a painting program ;)). Only the blue values of the pixels are used, the red and green values may be anything. Here's the actual map as it's read by the engine: 
And here are the controls: -arrows: walk around -alt: strafe modifier -keypad 0: walk faster -space: open doors and secrets -ctrl: fire your gun (you can shoot explosive barrels) -alt+enter: switch to fullscreen -0-9: select weapons (9 = lay mine, 0 = shoot fragments all around you) -escape: exit program P.S. Textures are ripped off from Wolf3D and Doom, and the ones I painted look like MS Paint graphics, I KNOW THAT THEY'RE UGLY!
