Customer Reviews

If you bought the game before

Then now it allows you to restore purchases. I had the problem where restore purchases timed out but then 3.02 (and now 3.0.3) fixed this. So people who are having this problem do try again. As for people moaning about the ads, just pay the £2/$2 and play the unrestricted version, its worth it especially with tails and knuckles and hidden areas of levels unlike before.

Please enable the ability to collect 7 chaos emeralds in normal mode rather than having to do level select to unlock the 7th one so I can be Super Sonic during the game. A mobile exclusive extra level would be awesome too like Sonic 2's Hidden Palace Zone but more original with 3 acts.

...the 3.0.4 update seems to indicate they've added the 7th emerald in but there doesn't seem to be one?? Just a gimmicky way of saying performance enhance and bug fixes?

Great touch conversion

This is a lesson in cross system emulation that many others could learn from. The graphics and music are smooth with no glitches and has little touches of nostalgia like letting you set the region box and cartridge design to either US, Japan or EU. The touch controls work well once you get used to them, it's just one button and a Dpad so it doesn't take long to adjust. It's free and the adverts aren't too intrusive if you don't want to pay to get rid of them. Classic game on your mobile.

Great Game / Mediocre Wrapping

The game itself is as great as ever but there are some issues with the app. I don't mind paying for ad-free but I don't expect to have to keep restoring purchases which is getting tiresome. The graphics outside of the game are poor, have little relation to the game and the interface is needlessly clunky. I seem to have lost all of my achievements in the last update. I would have preferred a Sonic Jam-style compilation with in-app purchases for the individual games
