Oh fine I'll answer
Lol
So if you view the code, navigate to
DEF XROT
DEF YROT
DEF ZROT
DEF POINT3D
These 4 functions make up the 3D engine in the game
XROT will rotate an x,y,z point around the x axis
What POINT3D does is it takes an x,y,z position, and gives you the x,y[,z] position of where it goes on screen
So yes I made the 3D engine, but it's very very easy to make
