About this game

A management simulation in which you take an old, run-down castle and turn it into a dastardly demon stronghold! Recruit unique monsters as your minions and vanquish adventurers who dare to enter your realm!

Install gargoyles, ritual altars, and other devilish decor to boost your castle's mystique and attract more monsters your way. Gift them food and other items to help them grow, and garner their support to fend off pesky adventurers.

You can also send your monster minions out to explore nearby dungeons and towns. They'll bring you back items and other loot, and maybe even some new allies!

As you progress, you can also start merging monsters together to make new ones.

And don't forget traps—essential equipment for proper castle defense! Develop a range of traps like sleep-inducing gas and heavy washbowls to thwart any who cross the threshold of your demonic haven! By placing and combining traps in imaginative ways, you can make your fortress of fiendishness virtually impregnable!

Fend off attacks from mighty adventurers and keep your minions sweet to become the biggest and baddest demon overlord of all time!

Demon Castle Story is a fun, chill management game with that classic Kairosoft charm. Building up your demon castle is satisfying, the pixel art is nice, and it’s easy to pick up for short sessions. It can get a little repetitive later on, but overall it’s a solid, cozy time. If its progression was more similar to Dungeon Village 2 it would be a perfect 5 of 5 stars for me.

This game is super cute and really fun! The monsters and decor have fun designs, and I enjoyed finding out what different monsters could evolve or be merged into. I just wish the little celebration animation had versions for the different overlords you can choose from! Already can't wait to start another demon castle and make it more efficient haha!

This game is absolutely addicting. It's a Dungeon game but with more monster capture elements. You can freely make and remake your base to look however you like and there's many reasons to make a new game when you've hit 15yrs (transfer +1 monster and wairo statue). Eventually it gets easier and easier to get 5 stars. There is also a hard mode if it's too easy. I wish there were more base customizing options for themed looks (lava rooms, graveyard rooms, beach, etc), but would recommend.
