Olivia's World: Crystal Keep PC Steam CD Key

About this licence

A story-driven tower defense RPG set n a peaceful fantasy world on the brink of elemental war. You play as a Guardian sworn to protect towns, kingdoms, and floating crystal isles from goblins, wargs, and corrupted armies. What begins as a routine defense quickly spirals into a wider conflict — one that challenges everything the world believes about its history… and its enemies. Tactical Defense Meets Real-Time Action Each map blends structured, wave-based tower defense with real-time Guardian combat. Place your defenses along defined enemy paths. Adapt to evolving waves. Survive escalating assaults as enemies push toward your exit point. Your spires automatically engage incoming threats, while you step into battle with powerful Guardian abilities when the tide turns. Victory comes from positioning, resource management, timing, and understanding enemy behaviour — not reflexes alone. Play
