Good Game. My SEGA Mega Drive doesn’t have ads though

I love the sega megadrive and genesis games but this stinks not gameplay wise but the fact that all of the ads come after every single act. It usually takes me 1-2.5 hours to complete sonic one (megadrive/genesis) but this takes days. Plus I think it’s getting to be a bit of a scam where you should just make it a game which isn’t free instead of having the ads here anyways. Could you also do sonic the hedgehog 3 and sonic and knuckles for the mobile App Store and google play? That’s my favourite and I would buy that game

Ads Ads Ads

Bought this game when it first came out, before the Sega Forever branding. It was great. Now it’s a constant fight against adverts.

I wasn’t able to restore my purchase when the first Sega Forever version came out. That was fixed with an update. Now I’ve updated to the latest version and it’s lost my purchase again! And once again I can’t restore it. Clicking restore purchase does absolutely nothing. Very disappointed. I even tried uninstalling the app(loosing all my progress) and reinstalling. This made the box for my password pop up when restoring purchase but after entering it....nothing. I still have adverts and the restore button is back to being nonfunctional.

Edit in response to developers reply: as I mentioned I HAVE purchased the game. Way back before any of the Sega Forever branding. I am no longer able to restore purchases with this update. Just freezes.

Developer Response ,

Hi, in addition to 3rd party ads, we will send you information about SEGA products we think you may be interested in. When you make a purchase in the game, it removes the 3rd party ads but you will still see news about SEGA games. If it is 3rd party ads that you are seeing, please contact us at with a screenshot and we'll investigate.
