Museum of Paranormal Phenomena is a relatively short parser made as an homage to the movie Ghostbusters. In the game, you visit the titular museum, whose rooms are decorated like scenes in the movie. Except some things seem out of place or missing. And Slimer keeps roaming around. You end the game by returning the rooms to their counterpart scenes. Knowledge of the movie isn't really required to complete the game (though it will help with speed), as the game only accepts one specific item in each room.
As is, it's a fine fetch-puzzle game, which is well built and without issue. But it didn't do much for me. It's definitely a game that plays on the nostalgia factor (hinting about the referenced movie at the start without explicitly mentioning it. So if you're not familiar with the movie (or if you don't enjoy it), the whole nudge-nudge-wink-wink will fall flat for you. The idea of having cleaning up the museum is neat, and I weirdly wondered when each room would come to life (or have some actual paranormal activities).
