Mighty and Ray please!!!!!


Can’t wait for Sonic Mania Plus, especially now that Mighty and Ray are going to be playable!!!!!
What would be fantastic is if this game and Sonic 1 got updated with Mighty and Ray as playable characters, it would make sense especially with Sonic Mania Plus on the way.

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, 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.
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!!!!!

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.

Sega Forever? Huh?


So Sonic 2, I bought the original version before Sonic 2 was included with SEGA Forever. Once I tried to start playing, my game kept freezing and wouldn’t restore purchase. After fixing this after a day, I was shocked to find out that the controls were just horrible. Knuckles was bad since his controls would have a long delay, I havent tried Tails, but with Sonic it was horrendous. The controls were just bad because each time it would either, delay my controls, not let me spin dash most of the time and couldn’t run and jump at the same time. There was no point updating an already good game to make it worse. Please fix this, since now there is no point playing this with bad controls.
