About this game

Chart the progess of Humanity through the ages, and guide their every discovery from the moment they kindle the first fire to the far future. Develop over 200 unique ideas across three different flavours of thought. Help your people to conquer or make peace with their enemies, explore and exploit the world, and develop projects to meet their needs.

Manage your tribe's choices to squeeze out more strength, or sit back and idle as your clan develop on their own. Advance as far as you can take your people, and then collect bonuses to improve future runs. Select varied challenges that change the way the game plays, and combine these challenges to create your own unique scenarios with big rewards.

I really wanted to like this but the help section is sparse and the "what affects what" isn't clear. I got to the option to do two challenges at once and it was so grindy that I stopped caring then forgot what I was even planning to do from the rewards. I'm normally an efficiency machine at incremental games but I just couldn't get a rhythm here. I think the potential is there though for sure.

this game is so simple and complex at the same time. It's a real time dump so be aware of that, but it's a fantastic game if you like idle games. I have no complaints about it at all. one feature I do wish it had though is a button for like a set load out. like if I'm about to close the game, I hit the button and the saved setup I have puts my ideas on the nodes I had it saved to. that would be fantastic.

Game is great but now it keeps popping up with random ads in the background doing constant noise and then suddenly showing a little window of the app I'm assuming that has an ad playing in the background. can't see the ad, but can hear it and the window, even after closing it out, constantly pops up blocking buttons. Before its said, I'm awarw its a free app, I'm just asking you to be upfront with your ads and not so obnoxious. I started worrying I had a virus at first until the window popped up

Thanks for your report. I want to be clear that this isn't intentional - ads should only show when you request them. There's no mechanism in the game to show ads at any other time. That said, you're the second user to report this issue and I've been investigating whether it's a bug in the ad plugin. I'm keeping on top of updates there.

What’s new

Fixed an issue that might cause ad completion to fail.
Fixed an issue in which an exploration timer would reset on app restart.
Changed new game startup to hopefully eliminate a rare issue in which exploration cards don't appear on the first run, making the gate unreachable.
Fixed an issue in which a late game bonus' name would flicker rapidly in the breakdown list.
Engine update.
