Okay game, but not as good as the first.
The truth must be told, and that is why I'll admit that I didn't spend too much time playing this game. I never owned it, but I played other peoples' cartridges of it.
I would probably give the graphics of this game a 9, since they're pretty decent for a 1988 game.
The learning curve would be less than 30 minutes before you learn how all of the controls work.
The pretty cool thing about this game is that there are secret doors in certain places in the levels, and they lead to some interesting areas.
My rating would be a 7, since good is pretty much the term of how I describe this game.
