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

Please add Game Gear version

I really hope that some Sega Game Gear Games become available as part of the Sega Forever Collection soon, especially Sonic Chaos and Sonic Triple Trouble.
It would be fantastic to play those games on the go again.

What would be a good way to bring some of the Game Gear games to the Sega Forever Collection, is if they were included with their Sega Mega Drive versions as in app purchases.
E.g. This game could include the Game Gear Version of Sonic 2.
Sonic 1 could include the Game Gear version of Sonic 1.
Streets of Rage could include the Game Gear version of Streets of Rage.
Streets of Rage 2 could include the Game Gear version of Streets of Rage 2.
Dynamite Headdy could include the Game Gear version of Dynamite Headdy.
Etc etc.
It makes perfect sense, think about it.

Then the games that are Game Gear exclusives such as Sonic Chaos and Sonic Triple Trouble could be released as their own individual apps.
This also makes perfect sense, think about it.

What would be fantastic is if Sonic Chaos and Sonic Triple Trouble were both Remastered with Knuckles as a playable character, that would be a dream come true.
Knuckles could use the same design he has in Sonic Triple Trouble for both games.

Keep up the fantastic work!!!!!

Awesome game! Play it all the time

Sonic 2 on mobile is one of the best Sonic games I've played. The graphics, the hidden palace zone and other stuff such as Knuckles make it a big 5 star alert.

I also love how Tails can actually FLY in this version of the game when being played on his own. In the Xbox version, he is just the same as Sonic therefore in that version Tails doesn't really have a speciality. I know I'm rating this on an iPad but maybe you could make it so Tails could fly on the Xbox too Sega? Thanks so much. All in All, brilliant game!
