About This Game

Olivia’s World: Crystal Keep

A story-driven tower defense RPG set in 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 as Distinct Guardians

Choose from a roster of unique Guardians, each with:

• Their own abilities and combat style

• Different strategic strengths and synergies with your defenses

• A personal role within the unfolding story

Every Guardian offers a new way to approach each defensive map, encouraging experimentation and replayability.

A Character-Driven Fantasy Story

As the war spreads, you’ll uncover a deeper narrative of forgotten history, fractured loyalty, and a mysterious enemy whose motivations are far more complex than they first appear.

This is not a story about stopping the end of the world.

It’s a story about balance, truth — and the cost of ignoring the past.

A Complete Experience

• Handcrafted wave-based levels

• Strategic structure placement and upgrades

• A clear beginning, middle, and end

• No endless grind

• No procedural filler

Olivia’s World: Crystal Keep is the first chapter of a larger saga — but it stands alone as a complete and self-contained tower defense experience.
