The basic gameplay is a solid numbers-going-up idler. However: - the unskippable ads are absurdly aggressive - there's no endgame at all; nothing happens once you run out of things to buy meaningfully (by which I mean everything at 5 gold stars). You don't even get a popup noting that you're done. - the prices rise higher than the list of number-names before you have everything maxed, meaning you'll be guessing a lot about how much "a lot!" really is towards the end
