Majuu no Ohkoku — About this game

Majuu no Ohkoku gives Condor and Labryna ranged weapons for a mostly linear journey between keys and exits. Collected blue orbs advance a power-up selection bar; activating the highlighted choice supplies the desired improvement. Dynamite accompanies normal shooting once obtained. The map shows the area while repeated dragon encounters interrupt the route toward the final confrontation.
