@Ethan-D Yes, you could make a dancing line game, but it won't actually be 3D. hyperPad is only a 2D game engine, but you can fake 3D by using isometric graphics. You'll have to take account of the z order of objects - objects with a higher z order will render over objects with a lower z order. For example, the floor could have 0 as the z order whereas the cube could have 1 as the z order; the cube will be on top of the ground. You can treat the z order as the vertical position in 3D space and it should do the trick.
