In this fiendishly difficult 1985 platformer, take on the role of the malefactorous mustelid Sam Stoat as he attempts to steal precious diamonds. Collect a bomb and match, jump across some perilous platforms, and find and blow the safe to claim your prize!
Hm, a weasel that sneaks around and thieves. Sly Cooper and Spy Fox come to mind! This came out after Monty Is Innocent!, so I will have to wait to play it till later.
