Editors' Notes

When in doubt, go faster!

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?

Mighty and Ray please!!!!


Can’t wait for Sonic Mania Plus, especially now that Mighty and Ray will be playable characters.
Since Mighty and Ray are going to be playable in Sonic Mania Plus, it would be fantastic if this game and Sonic 2 got an update with Mighty and Ray playable, think about it, it would make sense with Sonic Mania Plus on the way.

What would be fantastic for mobile devices is a Sonic Mania Runners, imagine that, a Sonic Mania version of Sonic Runners Adventure would be perfect for mobile devices.
With the following playable characters:
Speed Type:
Sonic, Amy, Mighty, Espio, Nack and Metal Sonic.
Fly Type:
Tails, Ray, Charmy, Bean and Tails Doll.
Power Type:
Knuckles, Honey, Vector, Bark and Metal Knuckles.
Then the following stages:
Speed Type:
Green Hill and Studiopolis.
Fly Type:
Flying Battery and Mirage Saloon.
Power Type:
Lava Reef and Press Garden.
Final Zone (All Types):
Titanic Monarch.

Also Sega please release Sonic 3 and Knuckles Remastered with Mighty, Ray, Classic Amy, Shadow, Silver and Metal Sonic as new playable characters, that would be a dream come true!!!!
If the soundtrack is causing legal issues, then please just release it with different soundtrack, it can’t be that hard.

Keep up the good work!!!!
