Okay wow absolutely loved this game! The balancing act of this game was so great. Just a perfect idle game. Made it to Eternal Empire and got a note that I wouldn't be able to go further without Prestige-ing -- where/how do I do that?
Found it, thanks! I made it the whole way through my first run without finding that menu! I love the amount of details and options in this game (especially the "incremental/idle" toggle option) and all the many names/titles of things as you move through the ages are well-thought-out. Tickled my neurospicy brain in the best way possible!
