About the Game

"Stop Breaking My Castle!" is a game designed from the perspective of monsters who are always getting beaten up.

Every day, heroes invade the peaceful Demon Lord’s castle, killing monsters and smashing the castle walls before leaving.
The Demon Lord and the monsters just want to live normal lives, but it’s been a long time since their home turned into someone else’s hunting ground for leveling up.

As the player, you become the Demon Lord, summoning and evolving monsters to stop the heroes.

Summon and place monsters.

Summon monsters to defend against invading heroes!

Heroes, driven by money and fame, have attacked the demon tribe who were living peacefully.

Auto Battle

Punish the heroes with the summoned monsters!

It's time to show the heroes, who were after gold and experience, the bitter taste of fear.

Monsters fight automatically, so strategic placement is necessary!

It’s not just the heroes who get to level up.

Punish the heroes who invade for experience points with even more powerful monsters!
