Way too many ads. I'll grant that it isn't the only game to have a ton of ads right now, but every other time I tap a box, I get an ad. If it was like one or two per level, that would be okay, but the way it is now is just objectively excessive. Other than that, it would be a very enjoyable game. And it's the #1 free game right now in its category, so less frequent ads would still make them some money. This just feels greedy.
