My races end randomly, my guy mills around, then suddenly I'm racing again.
Your races end randomly because you aren't in time for finishing the race. After the first person in the race crosses the finish line, there'll be a time limit of 30 seconds. If you won't be over the finish line in that time limit the race'll end without you finishing it.
How do I get back to a menu?
During a race click the gear in the top left and click quit. Otherwise just search for the "Back" button.
How do I upgrade my racer?
By getting XP Cards. If you get XP cards you can upgrade skills. You can get XP Cards out of Packs, which you'll get via Booster Packs. Booster Packs cost 500 gems each.
What does collecting crystals do for me?
Collecting crystals gives you money, gives you a small speed boost while 'dilloing' and earns you power-ups. You can use power-ups to disadvantage your opponents. Like 'Goonanas' which will slow down your opponent when he hits it.
Hope I helped you out :D
"Sady this game has nothing to do with sills anymore. It's just plainly standing last and pumping powerups to win. I find this very stupid and kind of game-breaking material."
Zen Mode maps. They're pure skills (and timing use of the Cloud power-ups).
