I have worked on MT3 a few times since getting back. A couple days ago, progress was super slow and I did not even export a video clip, much less upload one. Today I got much further, after having figured out a way to lift the bridge, and then I had the green cutter guy make some curved toothpicks which will be used for rail supports to keep the large marbles on track during the 2nd to last U-turn.
The little brother has kicked the chopstick ends back behind the stage so I don’t have to worry about not moving them anymore. His big brother is watching him.
After having raised the lower bridge, these three characters are about to walk up simultaneously (up) toward the stage.
