Level 8 and 9 are hard and you'd probably go crazy if you play this game for too long. So here's what you can do:
1.) If you feel overwhelmed by mushrooms: Pause the game for ~ 60 seconds. When you unpause again, all the stuff will float up and you'll have some time to breathe.
OR:
2.) Pause the game, return to the menu and quickly (!) press New Game again. Get a few fruits and repeat.
Getting to level 10 shouldn't be hard using these 2 methods. Remember to go for red apples, you get 3 points for them.
