Just played Air Zonk for the first time last night for about an hour or so.
It was really pretty fun, although I couldn't get past the boss lineup in level 6.  I got to the big dinosaur finally, but I kept dying.  I must have continued it at that level 4 times or more, and I was playing on easy mode too.  Oh well, I'll have to give it another go later this week and try to complete the game.
