Shadam Crusader - Harukanaru Oukoku

Defenders of Oasis is a turn-based RPG set in a fantasy world inspired by Arabian Nights and Zoroastrian lore. You control the Prince of Shadam as he assembles a party and embarks on a quest to thwart an evil empire led by Zahhak's descendant, who seeks to revive the dark god Ahriman using three holy rings. Gameplay features overhead exploration of villages and castles, where you converse with NPCs, purchase weapons and armor at shops, rest to recover HP and SP, and trigger random or story-based turn-based combat against up to three enemies. Combat involves strategic commands like attacks, spells, and the Prince's unique 'Run' escape option; characters gain experience points and items upon victory, with autosave to prevent loss.
