ALF: The First Adventure

ALF {short for Alien Life Form} was born on the planet Melmac. Alf arrived on Earth with a "bang" when his spaceship crashed through the roof of the Tanner family garage.
Alf now resides with the Tanners, having adopted many of Earth's 'strange' customs. Alf would also like to 'adopt' the family cat, Lucky, and turn him into feline mignon. So far, Lucky has managed to elude Alf's grasp, but Alf figures it's just a matter of time. After all, says Alf, "I'm only 230.
I've got another 300 years. Ha."
Alf desperately needs your help. Join Alf in a race against time as you scour the neighborhood collecting cats and spaceship parts, while avoiding Willie Tanner and the dreaded Dog Catcher. Sounds easy? Alf says, "Ha!"
How to Win
There are four levels of maze-like neighborhoods. You must navigate to win the game. Guide Alf through each, collecting all the necessary elements {4 cats, 2 spaceship parts and 1 key} to advance to the next level of play. You must complete all four levels before the clock reaches 24 hours.
How to Lose
Watch out for the Dog Catcher. Willie only bails you out of the pound three times, then you get put on a leash in the back yeard. Uh-oh, game's over.
