This game is not Clicker Heroes.
This game is not Adventure Capitalist.
This game is not simple.
This game is not a normal idle game. If you want to be able to make quick and easy progress, turn back now.
What this game is:
It's slow. You will not always feel like you are making progress, and if you aren't paying attention you can easily take a few steps backwards in terms of progression.
It's confusing. Instead of having one main currency and one prestige currency (for instance, Clicker Heroes has gold and Hero Souls), you have four main currencies that double as prestige currencies, based on a number of multipliers that are applied before or after your next rebirth, that may or may not be lower than your current ones. It's not impossible to figure out the way some reviews below are saying, but you won't be able to instantly glance at the game and know exactly what you're doing from the word go.
It's deep. You're given a big hit list of gods to defeat at the start, and in a way the entire list is just the tutorial-as you progress you continually find new mechanics, and just when the game seems like it's slowing down, something new appears that demands your attention. I've put many hours into this game, as you can see, and as of this writing I'm not done with the list yet-which means there's still more in the way of mechanics to unlock.
It's thoughtful. There are a number of systems, all of which tie into each other in different ways that create interesting combinations. Your level of skills is valuable for the special battle system as your skills become active abilities, but leveling them too much will increase your mystic level, which will make the enemies more challenging but not empower you because mystic is irrelevant to battles. Your Shadow Clones can fight in the Battle Tab, but pitting them against an opponent too powerful means they will die-but them dying increases your maximum number of clones on your next rebirth, so maybe you should let them be killed. Monuments increase your stats by quite a lot, but only after you have a lot of creations, so you need to buy them with divinity, which you get from the special battle system, or from the divinity generator. All of these feed into your ultimate goal of making upwards of six different sets of numerals grow to increasingly massive amounts, in order to complete your list of gods at Tyrant Overlord Baal and create a universe. Apparently, only then does the real game begin, but all this complexity occurs before that point. Hell, I've not even unlocked planets yet, which leads to some other ridiculous complication.
This game is not an ordinary clicker game. It's complicated and requires thoughtful decisions, with many sets of numbers that all affect each other in different ways rather than just one or two. If you just want to turn your brain off and watch big numbers become bigger ones, play Clicker Heroes (which, don't get me wrong, is a quality idle game). But, if you're ready to take the next step and see how mind-boggling interacting systems of numbers can be, give this one a shot.
Give it some time. You won't regret it.
