Garfield was a prototype, so it never got released to the general public. But thanks to some people and the kind folks over at Paws, Inc. (the people who handle Garfield), this game got to see the light of day, albeit on an emulator.
Level 1
Garfield goes after burgers. Since the programming for all the burger levels weren't done yet, Garfield suffers no consequence for being knocked on the back of the head by a burger.
Level 2
A potted plant is coming to get Garfield! If you hit the plant, you do lose a life. So the best bet is to duck by pressing down whenever a plant gets really close to Garfield.
Level 3
Who knows why Garfield is on the roof. But if you happen to get close to Odie, he'll lick you and you'll lose a life.
Level 4
Another burger level. This time the burgers go faster. If you happen to get hit by a burger at the right time on the right side of the screen, there will be a 50-point icon that will carry over to the next level and make it so the potted plant won't be there.
Level 5
Another plant level. The plants come at you faster.
Level 6
Fans of Garfield realize that if Nermal was dangling from the roof, Garfield probably wouldn't save him. If Jon would save him, Garfield would just try to mail Nermal to Abu Dhabi. But still, all you have to do is touch Nermal to double your points. Since it won't do anything for a few seconds, you'd probably think the game was over...
Level 7
But no! Garfield must have had some bad catnip, because he's jumping on Odie heads eating hamburgers. Hmmm.
Level 8
More potted plant dodging.
Level 9
More burger eating.
Level 10
Even more potted plant dodging.
Level 11
Potted plant dodging while jumping on heads of Odie clones.
