Very good unfolding game that consists of several different "features" that progress independently of each other, with rewards that boost all of the features coming at certain progress points. High focus on that unfolding nature, with a really great amount of depth/complexity coming the further you get into the game.
Extremely idle in nature---you'll likely be spending minimum one full day on each prestige, or even longer as you progress further in the game. IMO it does this very well, since each prestige typically brings a lot of progress with it, and since each feature prestiges independently from one another, you always have something to do.
Game is still in active development, but has a lot of content as of now. Definitely a long-term game, expect it to last you a number of months, not hours.
