Super sonic breaks the game 😂

If you get super sonic you can fly through the game without a care in the world besides falling into holes in hill top zone, super sonic is so broken that if you ported sonic 3 and knuckles hyper sonic would destroy the game, but back on topic super sonic is a god, well done if you have all the chaos emeralds and myself included it’s so fun going through the stages as super sonic except for metropolis zone where you can get squashed way to easily with super sonic and hill top zone is also annoying, but super sonic makes all the hard bosses *eyeballs chemical plant zone act 2’s boss and metropolis zone act 3’s boss* super easy (pun intended) but its annoying in metropolis zone because if you go to fast you can squash yourself but besides that really funny and broken😂😂😂 (also you can get super sonic before chemical plant zone)

Btw we all want sonic 3 and knuckles SEGA, make it happen by 2019

Curse you, Sega Forever!

Okay, so I got this a long time ago, and enjoyed it a lot. Sonic 2 is still a great game, and Christian Whitehead ported it really well to mobile.
...huh? You say that they've changed it? And that the port now has rubbish controls, ads, and is generally worse than before?
Oh, for crying out loud, Sega.
Nope. Not updating. I already lost Sonic CD to this, and I won't lose Sonic 2 too. Also, it's a pretty bad way to treat the guy who did this port in the first place by scrapping it for a worse one. Especially when he helped make one of the best games in Sonic history a few months ago.
Overall, it's fine for you to be porting new Mega Drive/Genesis games to mobile, but PLEASE don't touch the ones already on the App Store that are PERFECTLY FINE.


Mighty and Ray please!!!!!

What would be fantastic now that Sonic Mania Plus is out, is if Mighty and Ray were playable in this game, Sonic 1 and Sonic CD.

Also 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, Espio, Nack and Metal Sonic.
Fly Type:
Tails, Ray, Charmy, Bean and Tails Doll.
Power Type:
Knuckles, Mighty, 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.

Please Sega and Christian Whitehead, make Sonic Mania Runners for mobile devices, you know it makes sense.

Also 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 release it with different soundtrack, it can’t be that hard.

Keep up the good work!!!!!
