Elliot

A kind of unofficial sequel to E.T. The Extra-Terrestial in which Elliot has to save as many E.Ts as possible from their dying world, which is being bombarded by meteors.

If one of these meteors hits the ground, you lose a life. Save E.Ts and return them to the mothership for bonus points. When the timer runs out, it's onto the next level, which is a bit harder each time.
