Forgotten Worlds — About this game
Forgotten Worlds sends a flying warrior across an occupied world, with movement and aim handled separately. Your weapon fires automatically, leaving both buttons free to rotate the firing direction around a full circle. This lets you dodge one way while attacking another, but enemies and obstacles still drain your power when they hit. Defeated foes provide currency for Lucia's shops, where weapons and recovery items compete for the same money. A Mega-Crush can clear threats around you at a cost in power. Decide when to spend energy on an emergency attack and when to save it for surviving the next section.
