About Defend the Dragon Palace!

Dig. Grow. Defend.

Dig into the seabed and sea beasts are born from the soil. Kelp spreads, urchins graze on it, octopuses hunt the urchins. You never give them orders. All you can do is dig, and the ecosystem that grows becomes the wall protecting the Dragon Palace.

Eight species, one food chain

Kelp, Urchin, Octopus, Sea Firefly, Sea Bunny, Mermaid, Umibozu and Skeleton. What is born depends on which soil you dig. Nutrient-rich earth breeds kelp and urchins. Mana-soaked earth breeds sea bunnies and mermaids. They walk, eat and breed on their own schedule. Funnel the divers into a narrow corridor, or open a wide hall and let the swarm surround them. How you dig is your entire strategy.

The divers are coming

Fishermen, harpooners, monks, armored warriors, a turtle girl, and worse. Each has a favored tactic and a weakness, and each leaves a grave when it falls. Dig up the grave and the bones fight for you.

Princess Skills

Powers wielded by Otohime, the ruler of the Dragon Palace. Earn coins as you play and buy them from the shop on the title screen. Heal your beasts, level the dungeon with a quake, or carve several tiles in one strike. Eight skills, three levels each, one equipped at a time.
