You finished the game.

Meaning, you unlocked all the achievements.

You also paid money for the game to get all these achievements.

And now the only things that's missing is for the achievements to show on your Steam profile.

But they still don't.

What might be the issue?

For example, this player posted:

It's because the game is in the "Profile Features Limited" you can hover over the "?" on the store page to know what is not there, achievements is one of them that is locked.

Once the game gets a certain amount of sales it will be lifted, until then you can't use achievements on your profile, etc.

The same person ultimately concluded with:

So I paid for an achievement game to unlock 100% of the achievements but it doesnt even show bruh

Still has not had enough sales to get the "Profile Features Limited" off the store page, next time check before making a purchase.

P.S.
It's a fascinating little discussion, and you can read through all of it here:

The answer is, pretty much, nothing.

a) You can wait for the game to generate enough sales for it to remedy the issue. (Which is highly unlikely at this point)

b) You can demand your refund from Steam, if you haven't played the game for more than, what was it, 2 hours or something? (Which is highly unlikely at this point)

c) You can write a review in which you will explain how you were thrilled by this whole thing. (Which is highly unlikely at this point, or maybe not?)

d) You can, and apparently, you should, thoroughly investigate both the game and Steam's own rules and customs before buying a 99 cents achievement clicker game.

Enjoy!
