It is largely pay to win. You cannot unlock the powerful slimes without spending money. The upgrade tree is incredibly limited as well. EDIT: Since the developers responded, I wish to make something exceptionally clear. The best slimes absolutely are barred behind purchases.

Hello! Making in-game purchases only speeds up your progress, it's not the only way to get ahead in the game. There are plenty of other ways to earn in-game resources. So, if you're an active player, you can still compete with others. Good luck!

Cloud saves delete purchases when changing phone, pay to win mechanics are getting worse and worse. Otherwise an overall enjoyable concept for an idle game, was much better in the beginning before p2w got out of control. loosing a bunch of progress and purchases despite loading a cloud save was the nail in the coffin for me. Edit after developer comment: It is not the ads that I take issue with, it is the massive pay to win event and unlock mechanics.
