HELL DIFFICULT GAME AT FIRST, but I was able to make it to the end of the silver round in the tourney on my first day, so 2 hours well spent.
If you want to go fast, you need to get speed AND height when going for a dive. Don't touch the up/down key to adjust the altitude, just press down when you're going to dive. When you're about to crash, press the up key and you might be able to go right into a launch jump from there. In the beginning, Just launch yourself from the starting line and use the beginning to build speed
