Okay, I've beaten this game like one hundred times, I've gotten the spring morph and casemann morph. And have deciphered the code in the attic. But for some reason I always end up with an EXTRA red key. Now, I collect 6 red keys in the game every time, and only open 5 red doors. Does anybody know of a secret red door that I may be missing? A vent perhaps? Any help would be appreciated.
