Darn got there before me.

I also think the bottom is familiar.

I'll make a shot in the dark:
Ninja turtles!
(the rat/fox/dog on the left looks like Splinter)

No it's not Ninja Turtles.
But the gameplay is similar

EDIT:

Since there are over 15000 views and no has an idea of the game I posted in monochrome I solve this puzzle:

It's "Altered beast" on the C64!!! :bleh: :tomato:


EDIT2:
I'll go on with this game, but I have no clue if there's still anyone interested.
