Dragon Unit / Castle of Dragon — About this game
Dragon Unit gives one or two knights six timed stages on a rescue quest. New weapons include a mace, fire sword and axe, while pickups restore armour, extend time, increase speed or provide temporary invincibility. Four stages finish with a boss fight, but two instead require finding a key. The separate shield action creates a defensive choice alongside attacking and jumping through the route.
