The level selection screen shows all of the levels you've unlocked so far.
In Story Mode there are four backyards where the Black Bugs have taken control, and a total of 12 levels. Tumblebugs has a choice of Story Mode or Time Trial Mode. If you don't collect it, the Powerup will flash quickly, and eventually disappear. If you complete the group while the Powerup is active, you'll collect that Powerup. Occasionally, Powerup indicators will appear on bugs in the queue. When three or more of the same colour come in contact with each other, they are set free, possibly triggering other bugs to escape as part of a chain reaction. The player can save the bugs by firing a coloured bug from Tumble's back towards a group of two or more of the same coloured balls. When one bug reaches the opening, the player loses a life and the other bugs in the line quickly rush underground. The objective is to save all of the bugs rolling round the screen, before they reach the opening to the 'Black Bug Empires' underground lair.
