Welcome to the future! … Or is it the past? You start off your empire building adventure as a worker in the distant future who, thanks to a rather unfortunate mistake, finds themselves thrown back in time all the way to the beginning of humanity. This fun strategy game will test your business acumen and tycoon tendencies as you build the world’s cities and civilizations from the ground up. History in the making After you’re thrown back in time, you’ll need to meet and work with locals to build and grow your way to the top and return to the future – you’ll also need to keep an eye out for time crystals to collect at the end of each level to keep moving through the ages. Experience the evolution of civilization in this fantastic idle style game as you get a feel for history up close and personal. Get your business plan on – At each step of your journey, you’ll need to earn money by selling items or resources to the locals. As you progress through the eras those items will change, evolving as you move up in time to reflect modernization. You’ll need to strike the right balance and find the best strategy to maximize profits while also hiring more workers and expanding your offerings each time to progress as fast as possible. Staycation time – While your character may have been haplessly thrown back in time and is now working in a Medieval town or prehistoric society, you’re able to just sit back and relax all while leveling up, no matter where you are.
