Now that I've completed the game I have a few words to say about it.

Comparing it to Cookie clicker, it's definitely worse. But it's still a solid game to play. I see that a lot of people have issues with lost progress, however I didn't encounter any problems with it.
Early game is good, steady. Mid game is slow and it's hell, where I almost deleted the game a few times. You feel like you are making 0 progress. Late game however turned out okay. I was expecting a slow grind to get the last achievements. But in the end I got them really fast.
The upgrades are a bit weird. Half of them I don't even know what they do (and I'm pretty sure they don't do anything). Rainbow poop and corn poop don't do a single thing.

In the end, I recommend you get the game on sale. It's a solid cookie clicker idle game, just be wary that you may lose your progress.
