How do you beat level 18 on the worlds hardest game

As you guessed, you have to collect all of the 'coins' but in order to finish the level you have to around 3 times. 1st time: you collect the coins which are close to the borders only leaving the middle coins and the ones on the other side then you do the same when you come back to the beginning spot the you have to just use good reflexes and skills in order to collect the coins in the middle. There isn't really an easy way or even a short way so you have to be focused and have some spare time. I hope that helped and good luck!
