The Bubble Invasion is intended to stress you out. This version of the bubble game is designed with high frequency so you won't be able to play as slow as the previous versions. Shoot down all the bubbles before they hit the line at the bottom of the screen. The bubbles marked in the Tutorial will help you complete the task faster so you should try to shoot those bubbles.
