This one is called orbit, you have to simply avoid the planets with your comet. the first levels are simple but it quickly gets addictive.
I’m at level 10
lvl 8-proudly
level 12…it’s getting hard!
You’re not on level 12…level 8 is not possible!
I can not get past level 8 either. 
Just passed 8! Try just “dropping” it at the top of the screen above the big planet on the right.
Damn it Brian, I had things to do today!
Level 11 is impossible!!
I found out that when you play the game again (starting from level 1) the levels change. For example the first time i played level 1 showed a small planted near the upper left middle. The second time i played level 1 was a big planet in the center. All the other levels were different the second time around too.
Thread jack:
On the Itchy and Scratchy CD Rom, Is there a way to get out of the dungeon WITHOUT using the wizard key?
I say level 10 is piss annoying.
Hahaha. 
Ditto

i got to level 7 before my “there’s better stuff to do” meter ran out
