'Cheat' to get you past thin red pathways: line yourself up with the pathway, and jam yourself against the wall opposing the path. Take your cursor outside the game box, then bring it in from the opposite side. Your cursor will snap across to the wall opposite where it currently is. My hand is a bit too wobbly for those paths, so I had to 'think outside the box' to get past them...
I gave up on the one where you had to squeeze through a bunch of narrow red pathways, it's not so easy on a trackpad.
