I finally got a cube rotating using rotation matrix! W, A, S, D, Q, E, R, F. And arrow keys. Press space to start. Next I am working on collision sensing, and bug fixes. Unfortunately I didn't add depth sorting so sometimes the side that's on the back may seem in front. This is also my first 100% by me 3D engine.
