Wario Land 4 Parallel World- Domino Run Score Run (24190)

So this is ANOTHER of my favorite levels. As with the Roulette Land, it's easy to mess up- you have only one shot at every race, each one has a cash prize for winning, and then ending a race turns every gem in the room back off. Meaning that to get the highest score, you need to clear out all of the money along each course perfectly your first time through and still win.
This balance of strictness happens to be my jam, so I recorded this stage like ten times for fun.

You probably also noticed the gems I passed up at 3:18. On Hard Mode, there's no realistic way to grab those thanks to the added spiked enemies. Wario's puffy cheeks are too fat to squeeze past on the inside, it's impossible to cut the corners tight enough to reach them if you go around the outside, and if you try to fall and grab them from above, you'll lose the race to the domino chain, and miss out on the much larger rewards up top. It's sad, and very odd, but I tested it pretty extensively and can't come up with a better answer to it.
