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?

Sonic 3 and Knuckles Remastered please!!!!


Please release Sonic 3 and Knuckles Remastered!!!!!
If the sound track is causing legal issues, then release it with different soundtrack.
Also what would be amazing for Sonic 3 and Knuckles Remastered is if there were more playable characters!!!!
Say like you could unlock Classic Amy by completing the game, then you could get other characters as DLC, like Shadow, Silver and Metal Sonic etc, that would be a dream come true!!!!
Please Sega and Christian Whitehead, make it happen!!!!

Also what would be fantastic for iOS is a Sonic Mania side scrolling auto runner like Sonic Runners Adventure.
Imagine how amazing that would be!!!!
Each type of character could have 2 Zones each such as:
Speed Type:
Green Hill and Studiopolis.
Fly Type:
Flying Battery and Press Garden.
Power Type:
Lava Reef and Mirage Saloon.
Then have Titanic Monarch as the Final Zone which can be played with each type of character.
You could start off with Sonic, Tails and Knuckles as playable characters, then you could unlock other playable characters like Classic Amy, Shadow, Metal Sonic, Silver, Blaze, Espio, Charmy, Vector, Cream, Nack, Bean and Bark etc.
That would be fantastic!!!!
Keep up the good work!!!!
