it fine

It's just a mess overall.

There are huge gaps between content unlocks and most of that time is spent just waiting to farm points.
You can't do much to speed it up. You just wait for days to do something new.

In theory, you can do soft restarts to get some permanent buffs to make the progress faster, but these buffs are miniscule compared to the scale needed to unlock new content.
For example, you can soft restart 3 times to upgrade all of your demons' production by x10 or even x100, but to unlock the new content you need to farm 1000000 more of the demon currency.
Stuff like that.
The upgrades you get from soft restarts quickly become less and less efficient to get, so you're just stuck waiting to get new stuff.

Also there is an elaborate microtransaction menu with multiple power ups that permanently make the game easier/speed up your progress.
That made me think if the content gaps are that big on purpose, to push the player into buying power with real money.
Either that, or the dev is just bad at making idle games.

And if you are bad at making idle games, then why push monetization into it?
Try to make the game good first and then offer some way for players to support you if they like it (like NGU Idle, Antimatter Dimensions, Idle Slayer).
I don't expect the dev to be instantly great at making idlers, but having this wide of an assortment of power ups really makes this game seem like a cash grab.

The only good thing this game has going is the art direction. And that part is really good. I liked the overall theme and the different creature portraits.
But they can't carry the weight of the awful game design on their shoulders.

There are many, many better idle games out there.
This one just isn't worth your time.
