The workbot, that looks an awful lot like a helicopter, has to collect all the cells and return them to the platform. This has to be done within the time limit and without crashing. Doesn't sound too difficult, or does it? Wait till you reach the next levels. You can pick up more lives and time bonuses, that is good, that makes it a bit easier. The quicker you are, the more bonus points you'll receive and that's what it is all about, beating all your friends.
