Super Mario is always fun to play with. Choose a character and start the race. Several maps have to be finished in first place, so that you complete them. To unlock secret map you must have five keys. Press D button to accelerate, S- to brake A- to go backwards W- to jump or fly if get wings Q- to activate nitro and space bar to activate an item. At the begging it might be hard, because you dont have money to buy items and upgrades from the shop, but Im sure that you will manage. Hit a question mark box to obtain a hidden item and quickly grab it or lose it. There are many surprises: mushrooms for extra speed and coins stars and flowers to make your enemies dizzy wings to fly and coins. Music in background and everything else makes the game incredibly fun, so enjoy!
