Use arrow keys to move around, space to jump. If it runs slowly, try increasing "resolution", decreasing "culldist", and/or increasing "mindist". Note that each of these will decrease the quality of the graphics.
This is a refinement on previous versions of the 3d engine -- this one includes depth sorting [kinda], which means that objects that are further away will be drawn with the pen first, which makes objects that are in front of other objects actually look like they are in front from all angles. This version also adds a simple object system, which allows a group of 3d primitives [triangles, quads, and sprites] to be moved and drawn together. Currently [although there is no plan to change this], objects must be convex in shape. The next version will hopefully improve the method of sorting [the current one is a hack to account for objects on platforms] and add in collis
