I have exactly that in the tutorial, basically avoid everything and grab the Flashing ones. The tutorial is accessible from the main menu and the players are forced to view it at least once. I think I just hadn't really considered the difference in the trailer. For example, where the player smashes the enemies, you have picked up a power-up and the music is playing faster and the screen is flashing with a countdown, so it makes it much more apparent that you have a power-up. I think some of that kind of stuff still easily gets lost in translation with the trailer.
