Sonic 3 & K???

Taxman, you can port sonic CD, 1, 2 and 4 but not the third? Yes I've heard you have that copyrighted sonic 3 tracks because Micheal Jackson bad all that but just use the tracks you used / replaced in the PC version of sonic 3, it can't be that hard. Also I don't think mania needs a big port to IOS in my opinion, S3&K will do is and that's the whole retro saga complete and since you and the crew are kind of over with mania, why not spend the time to port S3&K to IOS; it maybe doesn't need to be done now since of Sonic Forces but after that, just make your fans happy again and port the third and final to , do it for us.

Nope a low 0.5

This is a warning ⚠️ please do not read the following comments if you are willing to pay to not get ads and can deal with the game freezing every time you beat a level!

So you can probably tell I’m super super annoyed with this app. I’ve played the actual version on the Mega Drive- Sega Genesis mini console and really enjoyed it. In actual gameplay on this app it isn’t too bad but if you are good at the game don’t download (yeah I know seems backwards doesn’t it) because every time you beat a level/stage it bombs you with ads, kicks you back into the main menu and freezes. So who needs the no save option? There is a horribly hard button layout that makes no sense. The Sega mega drive (or genesis depending on where you are) doesn’t have a circle pad does it? The answer is no it doesn’t. So why WHY in all the universe would you make the left side a joystick? It doesn’t make any sense so good luck spending money on a Bluetooth controller for your Apple device and more money on the ads. Mhm sounds pretty bad doesn’t it. If you’re still planning on downloading it then well you are pretty stubborn and are willing to give this piece of rubbish a go.

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
