"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.

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