Glorkbot and the Golden Key.
See little Glorkbot?  He’s carrying a key, and he has to get back all these nasty invaders without getting hit or he’ll lose his key.  If he manages to get past them, there’s a treasure chest full of energy crackers waiting for him on the other side.
I haven’t successfully done it yet, but this game is pretty awesome so far.
