About this app

Developer Description

Demon Castle Building Dungeon Management Simulation

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!

popups waste sooo much time. explore is an integral part of the game. why is it a partially randomized pick? I just love sitting there and canceling the roster over and over again. the leader's attack mechanic for ranged is dumb and ineffective. might as well be melee.

After playing this all the way through here are some thoughts: This game is fun, but a lot of little things could have been changed to make it way better. Ex. The game gives you TONS of monsters to try and level up with to few resources or to little upgraded stats to try and keep up with the attacking adventurers. Traps are key. Actually 2 traps are really key, arrows and goo. Monsters merge should cost money not monster points. There's plenty more but not enough space. Good but not their best

ok. so the castle star rating test, keeps getting interrupted by invasion. which is annoying and kinda gimmicky cuz the actual test itself is easy to clear. But tbh, the whole game is kinda easy. So in your second run, you can pretty much unlock everything and clear all within the high score time limit. Thats it. 2 runs and you're done. not much incentive to replay. So for me, its a pretty short game.

Not interesting enough that I'm expecting from Kairosoft. So many aspects are just being reused in this game from other previous entries.

Didn't enjoy the game, couldn't refund within 30 minutes of purchase. Google Support and KairoSupport both re-directed to seek the other party for refund support. Google Support Specialists claimed the money has already reached Kairosoft. Google claimed they were unable to refund even though the game was bought within 30 minutes. Directed to contact Kairosoft Support email directly. KairoSupport claimed they were unable to refund due to the digital nature of game purchase. Directed me to Google.
