Tower Dungeon

Story:

It takes place in a certain kingdom. The Kingsguard squadron challenges the "Dragon Tower," a massive building hovering in the center of the sky, in an attempt to rescue the kingdom's kidnapped princess, but they are stopped by strong demons. The adjacent hamlet provokes them in an attempt to refill the injured troops, and when a young guy is taken to the tower, things start to go wrong. A story about sword and sorcery and exploring labyrinths starts.
