Great Game


The game is based off the concept that you control a creature of your choosing and you have to defend your dungeon against knights, mages, archers, etc. You can also hire mercenaries to help defend against the onslaught. You can upgrade your dungeon and earn more money, have more health and more.

This has great gameplay mechanics and doesn't require an internet connection. This is great because I usually only play while going somewhere. This game is one of the few mobile games that I would be willing to pay money for. Money can easily breeze through the game for you if you can pay. Most of the features, though, are accessible by just playing the game (might take some time though!). Very fun and I remember playing this a couple months back and trying to find it on the App Store. All in all, I would highly recommend you try this game.

Not sure why so highly rated


I don’t understand the hype over this game. It is beyond boring to play with zero instructions on what to do. There is so much that has to be done after a dungeon is cleared and there’s no guidance on what any of it is. You spend more time doing upgrades, selling things, learning about your dungeon, and reinforcing it (none of which seem to make a difference) than you do actually defending the dungeon. Don’t let the teaser video fool you, the actual play is entirely automated, which means you have no control over what enemies are targeted or when your guys attack. I watched enemies make it to the dungeon wall when they could have been taken out earlier. Your sole job during battle is to activate special abilities once they fill up. Once you sit through the automated fight it’s back to spending five minutes upgrading stuff with no instructions, then repeat. I’ve had more fun watching paint dry. It hasn’t had an update in a year so apparently the developer is done. Spend your money elsewhere.

An actual GAME, not a scam to grind out IAPs


This is a rare thing: an actual game that you play that doesn’t try to get you to spend money every five minutes or artificially stall your progress to force you to spend money on upgrades. You don’t even need to be online to play.

You get five dudes, and they fling things at adventurers trying to invade your dungeon, and you try to grind out ways to make things run more efficiently. Good for numbers geeks and people who are a little more on the OCD end of things. It’s like running little battle simulations where you can tweak stuff to try and get better results each time. Much more interactive than other ‘idle’ games, and the math behind it all seems well thought out.

I like the style of the graphics. They fit well with the theme, and the actual action when a battle gets going is fun to watch.

Coding seems solid too. I haven’t had a single crash or glitch, and even the tool tips update on the fly. I’ve played a lot of games where the devs get sloppy and don’t put the time in on those little finishing touches, so good job.
