Editors’ Notes

We love rediscovering hedgehog history with this enhanced edition of one of Sonic’s greatest adventures. This game sizzles with all the sprawling levels and blazing speed you remember from the ’90s, but this classic platformer is better than ever on the App Store. With crisp widescreen graphics, tight controls, and awesome extra content, it’s just a blast.


Severe Graphical Issues + ADs

This game is seriously broken on my iPhone X. Some sprites aren’t completely transparent and have white boxes around them. Even worse, when I start to play the game, it’ll last about 10 seconds before the graphics go completely haywire and turn into flashing and rotating triangles. It’s so broken it almost seems fake, like it was done on purpose. These triangles aren’t just limited to a couple of sprites... no, the entire screen starts randomly convulsing with colors to the point where you can’t tell what’s going on and it’s completely unplayable.

Another issue: I purchased this game full price when it was first released. So there shouldn’t be ads every time I play it. There shouldn’t be a Sonic 4 Ep II ad whenever I start it up, and there shouldn’t be a Sonic Forces logo that pops up in the top left inexplicably after the menu animation.

The ads I could live with, but it’s the graphics issues that really make this a one star rating. The flashing triangles make it so you can’t even see the game, and there’s even another issue where the menu elements don’t space out correctly, so the act # ends up mashed in with the zone name which is already mashed into itself due to some other glitch. All in all, the serious bugs need to be fixed in order for me to recommend this game. In its current state, I’d skip it.


Debug mode broken

Very good, but for some reason debug mode doesn’t work. It only shows the coordinates under the pause button and when I try to quit to the main menu while in a special stage, the exit button just flashes forever and the game doesn’t go back to the main menu please fix these!!! Also when I return to the main menu from the title screen, an ad just pops up, and there are ads in the top left corner of the main menu. This happens even after i restored my purchase. It also happens with sonic 1 and 2. Also, the opening cutscene doesn’t play anymore when I start a new file. Just also remove the freaking ads, and there is a glitch in tidal tempest act 2 good future where that s tunnel thing that pulls you up, if you move left or right, sonic or tails gets stuck in the wall. And also, whatever happened to no save mode? And in this, sonic 1, and sonic 2, whenever I get a phone call or an alarm goes off, all the sound just muted and the only way to turn the volume back on is to restart the app
