I'm giving it 2 stars because it's a genuinely enjoyable game, the concept it great! But, it's really difficult to enjoy the game with the intense level of saturation of ads. Every 30 seconds you're watching an umpromted ad. While I understand the need to make profit off of advertising, such an intense amount of advertising is really jarring and frustrating. You really do spend more time waiting for ads to go away than playing the game.
