Ass with some other games, the quality button could be used as some sort of speed up button. It was a great game, I would however like to have a way to stop the flight, it takes very very long, and if you clicked "next" accidently, you have to wait a long time for it to stop again.
The 100k cash achievement doesn't seem to work for me.
When I flew into a set of spikes at 190557 feet, I became so angry I set a testing dummy on a motorcycle, ran him against a wall, activated a big rocket on his back, some weird penguin, switched of gravity, and blew five grenades up under his butt... It did help me ease my anger...
Try the earlier races after you've reached level 150 in all skills again. You will sometimes be so fast, you'll fly over all other obstacles, very funny :)
It would be very handy if there was a reset buttton, now every time I don't reach space in time, for example, I have to load it all over again... other than that, good game!
