I found that the controllers are very difficult due to the lack of friction in the floor, I would've liked a more stable car, the obstacles are very challenging as fiting in between is another mini game within the game
There's a simple trick you can use, that is you can always stick to the sides, most of the time they will be free. To get into the holes, you just have to double tap the key until you get into it, smooth sailing afterwards. I one got 3000 using this method. Hope you try it!
