Hi! My father remembered a while ago playing a game on Arcade machines (mid-80s, I think) that he found quite challenging. It had a mage on a later level that neither he nor any of his friends could defeat. The game was named Cougar or the like, he insists, but googling did not yield any useful result for me.
Sorry, I don't remember much, it's a while since he told me and we don't meet often. Maybe anyone still can help?
I won't mark this as "question / problem" since it would take long until I could give you the reputation points and I most probably would forget it until then.
