I like the game. It has good art and great mechanics, a great time killer. Although it does take time to gather resources, it's technically expected since this is an idle game. I especially love the dialogues between the characters. It's just witty and funny, especially when the henchmen interact with each other in the city. My favorite being Tommy, Scrapper, and Boa. Anyway, there's no harm trying this game out. It's fun!

A very enjoyable game with good humour and personality, although I quite quickly reached the point at which progress becomes either an interminable grind unless.younstart spending vast wads of cash on gems - especially when it comes to unlocking the higher tier (and mission-essential) henchmen. I feel like you could be afforded a *bit* more scope to complete things without just paying for it. Perhaps the ability to trade more flexibly between gems, corruptonite and henchman tokens?

Good game, if you are patient. Fun for and idle game but you need to be patient and work at each of the sections. My only problem is the extra mini games / events are almost impossible to fully feet and or get the better rewards for unlocking more of the game without paying.

Hands-down the best idle game available. Engaging gameplay, layers of strategy, well thought out design, great art/music, and a good dose of humor (without being silly).

Unlike most idle games where you spend months to try to make a shred of progress, you can fly though this game in a matter of weeks or days (depending on skill). Its super easy to pick up and learn, there are fantastic events that are well balanced (for any state of the game). Just when you think you have beaten the game there is always more to do and explore. The ads are optional, not in your face, and give rewards. This is a great game too pick up and learn, would strongly recommend!

After playing this game for about 5 months I still injoy it as much when I first got it. Yes there is some moments where you have to grind like unlocking a new supervillain or trying to get the special item in the 3 events that go with them that take alot of your attention and time but still this is the only idle game where I didn't get bored after playing for a week or less and I love the small conversations that the character's have or when they talk to them selves so 5 stars for you guys

About this app

Ever wanted to be the villain? To build a lair? Hire henchmen? Fight superheroes? Concoct dastardly plans? Raid a city? Or… take over the world?

No? What, really? Sure you do!
