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!

Another instant classic by Kairosoft The game comes off as an inverted version of Dungeon Village, but with a twist of building one large castle. I agree with other reviews that the first playthrough is rough, but the 2nd is where you'll really get the most out of it. seeing all the updated sprites makes me clamor for a sequel to Beastie Bay and/or High Sea Saga. The more stuff Kairosoft does with its cute little monsters and adventurers, the better.

So I have played all but two of Kairosofts games. There are meh ones good ones excellent ones. This one though? this one is /amazing/ it does what cavern adventures failed to do. I have cleared the game two times already and one year off of my third (just got my 5stars for the first time) and it's been like a week? I've been so addicted to this game. Thank you Devs I freaking love this game so much A++ top tier.

Long Replay game. I have every Kairosoft game to date and this is one model I've been waiting on. This is a proper slow Burn Dungeon building investment of time. worth the money.
