Not fun, but the first few levels have the satisfying quality of scrubbing a countertop. Until you run out of energy ten minutes in (Im not exaggerating). Popup hell, constantly advertising $5 lootboxes. There is a system to watch ads for free lootboxes that seems to be broken-- the app reloaded itself after the ad finished, and returning to the store asked for another ad to be watched. 2/5 seems generous.
