Sonic J

Project Overview


Sonic J is a Sonic The Hedgehog based Work-In-Progress fan-made game made by jean_tha_n00b (me) and has the purpose of being an unofficial sequel to the classic game, Sonic & Knuckles.

Two main characters are playable:
Sonic the Hedgehog,

and Miles "Tails" Prower.

Sonic the Hedgehog is owned by SEGA. I do not own the franchise as I am not affiliated with SEGA and Sonic Team. This is a non-profit fan game and it should not be sold. No copyright infringement is intended by any means.

Zone List (Available for now):
  • Jex Island Act 1
  • Tutorial
As you can see this demo is very small as it features only two levels and characters. But as updates still go, new content will arrive very soon.

Coming in the next release (v0.2.5):

  • Special Stages
  • Super Tails
  • Bug/glitch fixes & physics improvements
  • Improved camera (y and x margins being classic-accurate)
  • Improved ring loss (rings are being tossed like the classics, and extra rings will fly away like in Sonic Mania)
  • Secondary action key added
  • Story mode
  • Time attack mode
  • Extended menu (options, extras, etc.)
  • Saving/loading system
  • New Zone
  • Pause menu
  • Progress bar in multiplayer mode (PC ONLY)

Sprites are made by SEGA and/or Sonic Team. Here are people who ripped them and also made custom sprites.

Facundo gomez, Frario, Hivebrain, Techokami, Triangly, Dolphman, Divine Incest, Random Talking Bush, and myself for some sprite rips.

Most of the sprites used in the game are also edited/made by me!

Apparently there is an official Sonic game for Motorola called Sonic J, but I'm not sure if it was just announced and then cancelled or it was an actual Sonic game.

I am aware of that. I still have no idea about what could it actually be though. I mean, I thought of naming my fan game like that because I couldn't think of any other original name and I also thought naming it after my name could be cool ._.
