"Hehe, it’s me, Sugar! Better run, or you’re gonna die~!!"

Build your deck, play your cards, and overwhelm your foes with an endless horde of animals!

Discover different cards each time you play, and choose the best card for the situation!

Animals, buildings, spells, traps, and more—each category is packed with unique cards! Depending on how you combine them, you can build decks with unimaginable destructive power!

Defy logic!

The game is packed with ridiculous cards that seem like jokes!

We’re talking dogs that multiply with every summon, spells that duplicate your entire army, and even cards that let you play your whole hand twice!?

Pull off combos so broken they feel like cheating. Anything goes!

Fast-Paced Real-Time Battles

Watch your animals swarm the battlefield in real-time! The controls are simple, but with the right setup, infinite combos are yours to command.

Combine your cards with powerful Relics to supercharge your deck and unleash explosive synergies. The only limit is your imagination!

A New Map Every Run

If it’s a roguelike game, there’s no way it doesn’t have random elements!
Overdungeon changes every time you play!

Every card that appears, every enemy you face, every event that unfolds in the dungeon, and even the places where you can take a break—they all change every time you play, so no two adventures are ever the same!
