The game itself is actually really addicting. My problem is the ads are absolutely ridiculous. You have to spend $10 to not have to watch a 30 second ad after every single level, and even then the game still forces you to watch ads to get upgrades, even if you'd rather just buy them with in-game currency. And you still have to watch an ad if you want 3x the currency for completing levels, even tho you spent 10 damn dollars to not have to. Basically an ad simulator
