I have made this cool raycasting engine where there's vertica movement! I am posting it here because sadly, only ONE person saw it, and it was a friend of mine, so it doesn't really count. It's a pretty cool engine, there some bugs with it though, and looking up and down is off.


there's a screenshot from it (though don't expect that high of a resolution and still have a decent framerate)
anyway, here is the link
