Giant Ads take up half the screen and cover up the jump button. I love the game otherwise and will change my review if you change the ad placement. I'm used to games having some ads, but this is frikkin unbelievable! I click close ad, it asks me why, I tell I select it covered up content. Google says it will remove ad, then half a second later, another appears in it's place! Pretty keen way to make 3 bucks for the app purchase, Sega.
