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!

I've been obsessed with this game since I got it. I have hundreds of hours playing. The gameplay is incredibly fun, and the challenges are unique and challenging! There's a lot to learn throughout the game but it's never overwhelming. I wish I could've paid more for this game. it's truly that good. The only real criticism I have about Demon Castle Story is that you have to have a wall behind certain traps so they can't be accessed from the other side, but it doesn't take away from the game.

I really love this game. The things I found really fun: building rooms piece by piece and trying to plan ahead for future monsters and decorations, creating all kinds of trap rooms and watching how effective they are, plotting demise instead of hospitality is a fun twist, I didn't realize I was craving violence in kairosoft games. It's been very fun and my favorite of their games. Can't wait to try out the dungeon adventuring ones after I finish this one.

Very repetitive gameplay. So basically you try your best to survive 'Story waves' , explore dungeons repeatedly so you can lvl the dungeon up, place traps in your dungeon, constantly interrupted by pop ups that the game feels like it needs to notify you of the most trivial things. Merge a few pets here and there, There that's the game. And you do it all over again in a new game+ mode with your selected OP monster. This end game loop is very disappointing unlike DV2.
