Too many ads!!!!!!!!!!!!!!

I loved this game when I first downloaded it a year ago. Then it started getting a bit slow, so I deleted it and reinstalled it. I’m fine with it being a tiny bit slower than I like it, which was actually what was happening, but when I reinstalled it, it said pay for ad free. 2.00 wasn’t worth it on a game, so I played ad supported. There are about 10x as many ads as I thought there would be. I thought it would be a video here and there, about 15 seconds long, but there’s an ad pretty much every time it needs to load, and they are all 30 seconds! I am very annoyed, as the description says it was the original sonic, but the original sonic had no ads!

Mr.ihateads ,

Can't play ad free. Help!

So, I bought this game on my iPad with the same account I am using right now. I downloaded it on my iPhone and it was fine. But, when I came back to it, it prompted me to either play the ad supported version or the ad free version. I was confused as to why it prompted me even though I payed for it previously, so naturally, is clicked on the restore purchase button. I Input my password for my Apple ID and everything (The same one I bought this game with). I waited, and I waited, and I waited. Nothing happened. Now I am forced to play the horrible ad supported version even though I paid for this app. If I have to pay for no adds with the game I PURCHASED, you can forget it.
