To answer your question about what the Tower of Tims does. You can actually pick up a Tim and drop it into the machine or wait until the Tims naturally jump into the machine themselves. It acts like an obstacle course/marble run for them. When you jump on the elevator platform you get for one of the other Tim wheel sub-objectives it takes you up and brings you into a cinematic camera view. From there you can use the right stick to move around and look at the Tims interacting with the tower. I don't think it really does much more, but in the demo they capped you out at 500 ticks which opened up the 2nd part of the Tower of Tims. Still couldn't figure out what the trampolines you get do.
