I wanted to challenge myself and tried to do an original implentation. It most probably has been done by someone before but it felt good being able to do it by myself nevertheless.
Instead of directly moving the cube with the arrow keys, I used a sphere (and called it Rolly :P) and it’s the ground plane that moves its rotation with the mouse movement and Rolly with it. Hopefully it allows for some engaging gameplay and it doesn’t clash with too many things that Rick implements in the videos.
