Ad simulator: the game. Seriously, the number of ads is insane. There's ads on the opening screen, there's ads at the bottom of the screen, the top of the screen, ads if you want a hint, ads if you need more time, ads if you die, ads if you win. Some of the levels felt purposely unwinnable on the first try and I have a suspicious feeling it's to make people have to restart the level so the game can show them another ad. The puzzles aren't even that great. Don't waste your time on it.

The puzzles aren't fun or intuitive, and even the levels it warns as being scary are really not. You only get one free hint and have to either pay or watch ads for any other hints. There are ads constantly, too. In the level select, when you win a level, when you lose a level, banner ads, I've seen more ads than I've had seconds of fun playing this after accidentally pressing install.

advertising is expected with these games. my annoyance comes from the ballerina level. if you don't touch the puzzle pieces exactly then the monster gets you. which is so annoying as the puzzle pieces are super small and some are hidden which is even more infuriating. either show all the pieces or get rid of the monster getting you if you touch ANYWHERE on the screen. so annoying I rage quit a few times because of it. the rest of the game is very fun. doesn't always make sense, aggressive ads.
