GOAT of incremental games, in my honest opinion, albeit the start being very slow to get through.
Don't look at my current low hour count, as I played a lot on the web version before the Reality update/steam release, but didn't keep my saves anywhere ;w;

The start is pretty "slow" in this game, imho, and requires you to be pretty active instead of merely idling outside the game window. As you get progress, you unlock autobuyers through challenges, after your first infinity, which in their initial state have too high of an interval to be useful for idling, and it will take you a while to get through the Tickspeed, Dimboost, and Galaxy challenges.

There are multiple prestige tiers which have their own challenges, autobuyers, multipliers, et cetera.
Those are: Infinity, Eternity, Reality. Not exactly a prestige layer, but later in the game you'll also reach Time and time dilation, after Eternity and before Reality.

You have achievements connected to your steam account, which give a multiplier to your dimensions as you get more of them, some of which give an extra reward for obtaining.
There are also secret achievements, which don't tell you how to obtain them, only listing a cryptic achievement name. Those do not give any rewards, and are purely for satisfaction.

There are several keybinds for helping yourself get to certain points faster, specifically the M key, which buys max of every dimension and tickspeed upgrades, D for dimboosts, and G for galaxies.
