Dragon Crystal - Tsurani no Meikyuu (Japan)

When you boot the game, the title screen is in Japanese but the menu options are straightforward. Press Start to begin a new game, and you'll be dropped into a randomly generated dungeon. Your goal is to descend through multiple floors, fighting monsters with your equipped weapon, collecting gold and items, and eventually reaching the final floor to defeat the boss.

Movement is turn-based; each step triggers an enemy action, so you need to plan your positioning. The B button swings your weapon, and you can pick up items by walking over them. Potions heal you, and armor increases defense. Be careful about hunger - your character gets hungry over time, and you need to find food to keep going. If you die, it's game over and you start a fresh dungeon from scratch. This is a true roguelike experience on the Game Gear.
