The game's got many, many nearly-impossible challenges. I had to redo one race over 200 times, and that was on the easy skill level. The controls are sloppy, and so are the flight dynamics. It's often extremely aggrivating.
That aside, I think I like it. I don't think I'd play it again, though.... I wanted to, but after that 200-failure race, I'll never do that again, unless they fix it.
