You'd get to a certain point where there's a room with an NPC. It's impossible to get out of the room (too high to jump, you don't have the ability to fly yet).

You'd get to a certain point where there's a room with an NPC. It's impossible to get out of the room (too high to jump, you don't have the ability to fly yet). The NPC tells you that you're missing an important item. I got in touch with Michael Denio, the creator of Captain Comic, years later and he told me that the "important item" is the game itself (and was kind enough to offer to send me a physical copy of the game by himself). I think it's one of the earliest examples of a game pretending to be properly cracked, yet ending up in an unwinnable state, misleading the crackers.
