This is my first ever 3D cube and it took a while to figure out but eventually i got it. Controls - Arrows to move around cube - W/S to change cube height - A/D to change cube width - Z/X to zoom in/out - C/V to change cube thickness - F/G to change cube length - E/R to change cube brightness - Q to change cube color Unfortunately there is no rotation controls because idk how to do that stuff yet.
I might "try to'' make a 3D platformer game with this mechanic but i'm still not very good at 3D but after a bit of practice and stuff to understand how everything about 3D works i might be able to make better 3D things.
