Conquest of the Crystal Palace

Conquest of the Crystal Palce (original Japanese title: Matendouji) is a side-scrolling Platform Game released on the Nintendo Entertainment System in 1990.

The realm of the Crystal Palace was once a thriving kingdom, until the evil war spirit Zaras came and started wreaking havoc, causing the inhabitants of the palace to run for their lives. One young swordman, Farron, comes forward along with his faithful guardian dog Zap in order to defeat the demon and restore peace to the kingdom.

The game has five levels where Farron will jump, hack and slash his way through enemies and encounter bosses. From time to time, he can purchase items from a shopkeeper named Kim, who will also brief him on the current situation around the Crystal Palace, if he so asks.

This game uses the following tropes:

 * A Boy, His Sword and His Dog
 * Anime Chinese Girl: Kim, complete with tying her hair in buns.
 * Canine Companion: Zap
 * Dual Boss: Kentar and Kellix, the first bosses.
 * Fastball Special: If you use the Dog Whistle while Zap is on the screen, you can launch him into enemies at high speed.
 * Flunky Boss: The third stage boss.
 * Meganekko: Kim, when newsreading and when explaining how the special weapons work.
 * Non Lethal Bottomless Pits: The two castle stages (the second and fifth) have them. Instead of dying, you get bumped back to the last (invisible) checkpoint you passed.
 * Precision Guided Boomerang: The Boomerang Annihilator magic weapon has short range, but will eventually return to Farron no matter where he is on the screen. With clever jumping, he can make the bullet orbit around him (à la Ryu from the NES Ninja Gaiden games).
 * Save the Princess: An optional challenge, but if you do complete it, you'll get the powerful Moon Mirror, which destroys weak enemies instantly.
 * Smart Bomb: The Moon Mirror.
 * Victory Pose
 * Video Game Cruelty Punishment: If you try to buy an item several times when you don't have enough money for it, Kim gets angry and throws you out of the shop.
 * Womb Level: The third level, the Lair of Hungry Ghosts.
