Need new update. Can’t finish zone.

What’s good sega and sonic team. I love you sonic games I have them all sonic 1 2 and cd even got two copies of sonic mania for the switch and ps4 plus sonic 4 ep 1and two (y’all need ep 3 just saying) but look in scrap brain zone act 2 at the end it have a glitch in it (again) where when you get done with the zone and moving in it the cut seen right before act 3 begin the camera movies all the way up where you can’t see it and when get to eggman where he jumps on the switch to drop you in to act 3 of scrap brain zone you automatically die and have to start the act all over again. And also when you get out of the game and goes back in or restart that act you lose a life and that’s a lil uncool so can y’all plz update this app again plz. Coming from a big sonic fan since the early 90’s the game need to fix its bugs fast. And also side note can y’all plz come on out with a mobile port of sonic3k plz that game is way to cool to just let it past yea I and everyone else know by that now that MJ made the songs for sonic 3 and not in for knuckles part of the game. But at least let us download part or the whole thing to our phones and tablets plz thanks much love from one of your fans of the sonic’s series.

Wonderful port, terrible controls

I've only played the free version, but I absolutely love this port of the game! The screen is zoomed out so you can see a lot more clearly and it's incredible to finally play Sonic 1 with the spin dash rather than the mediocre emulations of the original genesis title you see everywhere. In the free version, I haven't found the ads to be intrusive at all. I heard the premium version still has ads which definitely needs to be fixed, but other than that, the inclusion of Tails and Knuckles seems well worth the money.

There's just one major problem preventing me from buying the game: controls. I get that it's a mobile app, so there's not much you can really do, but I cannot stand using on-screen buttons for game like this. Every time I try to turn around, I accidentally end up rolling, often leading to me rolling right off into a spike or pit. Similarly, I might just be trying to jump forward but accidentally spin dash, or roll and suddenly lose all of my momentum.

I would absolutely love if this port could be made available on consoles and/or through Steam. I would love to play such a wonderful port the way it deserves to be played! Maybe if Sonic Mania is successful?

It’s Still Sonic 1

Christian Whiteheadand his team have provided the same classic Sonic game that kick-started SEGA’s mascot into the spotlight, and they have also made substancial improvements along the way. Widescreen gives you a much better view of what’s ahead and how to react, a stable framerate makes the controls buttery-smooth, and the inclusion of the spin dash makes certain sectiona a lot less of a hassle. The options to play as Tails and Knuckles are nice touches as well, allowing you to explore the levels in ways you never have before.
All that said, while the game is still the classic Sonic 1, that means it has many of the downsides of the original that no remake can fix. Save for Green Hill, the overall level design leaves7 something to be desired (Marble and Labrinth are especially boring), the bosses are beyond easy to beat, and the special stages give me headaches from two angles; one comes from the constant spinning of the stage, and the other comes from how downfight frustrating they are.
Overall, the downsides are mostly mostly mitigated by the touch-ups from mobile port, and it’s worth trying out if you haven’t played Sonic 1 before.
