It's really cute and gameplay is simple, but right from the start I got the impression that the only income that is actually high enough to have an impact on gameplay comes from watching ads. It feels like I'm spending more time watching ads for "bonuses" than actually playing the game. You can opt out, they're not forced on you, you just choose not to tap on them or spend the real world money on gems to skip them so it gets a couple of stars, but I've uninstalled. Not for me.
