If you boot up the game for the first time, you will be granted with the All files access menu with a list of applications present on your device.

Search for Sonic Jump Revival and then enable Allow access to manage all files. If you have done it correctly, you can hear the intro jingle in the background.

The files access permission is necessary for saving your game progress, options and map files.

If the game runs at a low speed, it is due to your device not being powerful enough to run the game at a higher frame rate. Also, the game lacks modern hardware optimizations and the more pixels the game draws on screen, the more the game might slowdown. This problem especially occurs during Jungle Zone.

There are multiple ways of solving the slowdown:

A) Set the FPS option to 16.7 (keep in mind that you can't resume your stage progress during the pause menu).

B) If you play on a tablet, you can switch the screen orientation to landscape in order for your device to prevent drawing the game frame by frame.

C) If you can change the screen resolution of your device, set it at a lower screen resolution.

For more information, check out the Frame Rate Increase project page.

Because the game is designed for older Android devices, you may encounter an "Unsafe app blocked" message. When this occurs, press "Install anyway" to proceed.

If the problem still persists, contact Furrican via the Game Jolt/itch.io project page, or via the Contact menu.

Yes. Like many Sonic fangames, this game does not contain any malware or other malicious programs whatsoever.

Of course. To do so, you need an Android emulator (like BlueStacks).

If your game controller doesn't work, make sure that it is well connected.

Also, keep in mind that the gamepad and keyboard controls are not working correctly after entering the Map Editor or an Internet link. Only the left stick, D-Pad and arrow keys are still functional.

No. Sonic Jump Revival is actually a mod of an already existing Android port of Sonic Jump.
This Android port was released in 2011 via a service named Puyo Puyo! Sega. This service is provided by SEGA exclusively for Japanese mobile phones.

The Android port of Sonic Jump has issues with some of its music and sound effects. Some .mid instruments sound too loud.

Because of this, some music and the attack sound effect needed to be replaced by better audio quality.
The game now contains .ogg files, instead of .mid.

When booting Sonic Jump Revival for the first time, the game asks you for permission to access file data. If you allow permission, folders will be created.

A folder named io.github.sonicmobirev.sonicjumprevival will be created in the Android/media folder. And another folder named SonicJump will be created in the Documents folder. The Documents/SonicJump directory is where your save file is located (sj_save.dat).

Sonic Jump Revival has begun development by November 2025 and has a fluid development cycle. Therefore, it took approximately 10 months for Sonic jump Revival to be completed.

The problem mostly comes from the CONFIG menu. If the stage name and graphics aren't changed, make sure to configure all settings before saving.

Sometimes, if the stage layout isn't changed despite modification before saving, it is possible that the game hasn't loaded the stage correctly. If so, go back to the Map Editor, load your map and save it again.

If you have selected a custom music and checked this option, the music takes time to load when playing the stage, because the custom music are stored in an external library.

If you have no music played during stages, you can bring the regular game soundtrack back by saving your map as a .bin file.

The map files are located in the SonicJump subfolder. This folder is most probably located in the ⤓ DOWNLOAD folder of your internal device.

Also, because map files don't overwrite anytime you save, you might ended up with a lot of duplicated files. But the file with the biggest number in ( ) has to be the most recent one.

You need to organize your files to avoid confusion. For better organization, make sure to store and backup your latest map file before starting making a new map.

If the New Issue menu doesn't let you select labels, your issue won't be labeled as a custom map after saving in the repository and your issue won't be visible.

However, you can still find your issue by removing the Custom map label of the repository search bar.

If you want your issue to be labeled while you can't, try to contact GdGohan to inform him of the issue.

It seems like there is a problem with either the game code or the GitHub connectivity. Unfortunately, we currently don't know for sure where the problem lies.

In the meantime, you can still download the custom maps outside of the game application and replace the decided_map.txt file from the game assets using the source code.
