Promise Mascot Agency update adds Tony Hawk-level truck rail grinding I didn't know I needed, and new difficulty modes

Promise Mascot Agency, Kaizen Game Works' thing about running a business that revolves around costumed weirdos, fairly intense menu shuffling and a lot of driving around, has gotten a free update that adds in a host of new features. The ability to grind along rails like Michi's truck's a skateboard, for instance.
Sure, you can already unlock the ability to fly said truck around the spooky Japanese countryside, but come on, if there's something every management game needs, it's tricks from the X Games.
