I'm just asking because I don't see a lot of Raycaster games on here and the one Raycaster game there is I love so much, so I wish for more. .~.
Calc84's engine is fairly simple to work with. Actually making your own is a different story, but it's probably just a lack of ideas for a game to make with it.
You could convert the built-in 3D dungeon game.
I meant to replace the old graphics engine with raycasting. You could keep the map, and the enemy battle code.
