The game is quite fun and a really neat way to speed up time, however ads are relentless, at least in my experience each time you build an island you get one, spent too much time without touching the phone? An ad. I get it, revenue and tbh, it's one of the few games I'm willing to get a forced ad on, just not every 20 seconds. Maybe one every 10 minutes would be nice. Or one each time you open the game after closing the app
