''Moon Crystal'' is a 1992 platform game for the NES by Hect, who are more known for their puzzle games. The game was released in Japan only, though it was advertised as a coming release in the U.S. In this game, you play as Ricky Slater to retrieve the moon crystal and rescue your father and other people from the local nobleman Count Crimson. The game is known for both its amazing animations (which make the game seem akin to ''PrinceOfPersia'') and its detailed storyline.

'''Video game-related tropes of Moon Crystal :'''

* OneUp: One of the items you can collect.
* AnimeHair: Ricky has that kind of hair.
* AstralProjection: [[spoiler: Rosina]].
* BottomlessPits: Present in most levels.
* ChainReactionDestruction: No matter if the boss is made of flesh or metal, it gives nice chain of explosions upon running out of hearts.
* CollisionDamage
* DefeatEqualsExplosion: Every enemy.
* DemBones: As the fifth stage's skeleton enemies make clear, Crimson's ''already'' putting the Lunasystem to work.
* DirectionallySolidPlatforms: One should not worry about hitting their head against a branch they are trying to jump on.
* DoubleJump: It's possible to double jump after getting a boots powerup.
* [[spoiler: EvilutionaryBiologist: Crimson is perfectly aware that the Moon Crystal doesn't just revitalize the dead, but also amplifies the qualities of the living. His plan is to use the Lunasystem to ''constantly'' irradiate human beings to turn them into superior life forms. His first attempt with Merle fails on account of Rosina disengaging the Lunasystem. His second attempt involves ''[[OneWingedAngel himself]]''.]]
* FlashOfPain: Hitting bosses briefly whitens up the entire screen.
* {{Fireballs}}: One of the enemies which you can surprisingly destroy with a sword.
* FloatingPlatforms: Many platforms levitate mid-air.
* GangplankGalleon: The fourth stage.
* GiantSpider: One of the enemies that is encountered early on.
* HeartContainer: One of the items you can get.
* HighClassGlass: Count Crimson wears a monocle.
* TheIgor: After the second level, it's shown that Count Crimson has that kind of assistant.
* InconvenientlyPlacedConveyorBelt: These are encountered in the stage 5.

* [[spoiler: {{Necromantic}}: Although never really stated, the cutscene where Rosina disengages the Lunasystem implies that Crimson's StartOfDarkness was bringing back his long-dead daughter--the same Rosina. [[ReplacementGoldfish Unfortunately, that wasn't enough for him.]] Considering his boasts of creating life superior to humans, it's very possible that his ultimate goal is to completely remove from the world the mortality that once stole Rosina from him...[[CameBackWrong no matter what]] [[OneWingedAngel life looks like afterwards]].]]
* NiceHat: Count Crimson.
* MercyInvincibility: After getting hit.
* [[spoiler: OneWingedAngel: When Crimson draws upon the power of the full moon-affected Moon Crystal to affect himself, he transforms into a [[EldritchAbomination demonic horror]] spewing fire and poison.]]
