aww, whats the matter sonic? YOU CANT CATCH ME? HAHAHA

i help with this game its so tuff

 Hi Darkfoxx! I really enjoy Sonic: Phantom Corruption, but I recently died in the sonic chase right as I figured out the strategy to beat it. Could you consider adding a New Game and Continue Game option in a future update? It would give players a second chance to fix their mistakes without losing all their progress. Thanks for the great game!

Game good, big potential. I like the follower character trying to kill you mechanic, i'd love to see more games do that. Also, being able to skip cutscenes would be nice. Got 2 minor bugs to report, touching the top of a level causes it to restart. And in Scrap Brain Act 3 if Sonic dies he tries to recover like Tails instead of teleporting.

Peak Goodness?

SONIC: Phantom Corruption is the biggest Sonic horror fangame I have ever created. It is my passion project and I have put a lot of dedication into it. I created this project to unleash my creativity, coding skills and to bring my ideas to life, while hoping someone at least will be interested in them.

I want to thank everyone who supported me and project in any way possible. This support gave me hope to continue working on this project till the very end, and I truly appreciate it!


PLOT:

After a long time period of investigation, Doctor Eggman discovered the PHANTOM RUBY.

It is a unique artifact which hides a huge amount of energy, so powerful that it surpasses the chaos energy. That can be used to overpower the host and grand them unique abilities or manipulate an opponent by creating illusions so real to them that can be harmful even. However, its use should be wise and limited, otherwise things will go out of control.

Eggman's experiment on the phantom ruby was a failure, causing the destruction of all his base systems, while the ruby began emitting energy uncontrollably. It possessed Sonic...

Ever since then, the corruption of the phantom energy slowly took over both Sonic's mind and body. His fur was getting darker, while his spirit was getting trapped more and more within his subconscious, allowing the phantom energy to take full control.

Now, it is up to Sonic's friends to discover the truth and find a solution in order to stop the ultimate chaos from spreading.

I highly recommend you download version 2.2 (or latest) so you won't encounter the same glitch with Sally again.

In case you died as Amy and now you're stuck with Sally in the chapter select, read the article:

Patch 2.2:

-Corrected some spelling mistakes

-When you die as Amy, you will be taken to the end of demo screen, not the chapter select (that causes an error in which you have to choose sally even tho she's not playable, so it glitches)

Patch 2.1:

-Fixed a minor issue with Knuckles glitching after using drop attack on fireball bouncer.

-When Knuckles glitches out of the frame, it will restart the stage, not the whole game.

I recommend getting the latest build if you haven't played yet.

THE NEW DEMO IS NOW AVAILABLE TO DOWNLOAD!

Do make sure to report any glitches you find, in order for me to fix them ASAP.

Have fun with this while waiting for the full part 1!

Also here is an image of the current progress!

What's better than Sonic's copy? THE COPY'S COPY!

Posting this on gamejolt as well.

If you want to join my discord, check the pinned post in the game page. I post stuff there as well.

If you watched my latest teaser video, you probably noticed the side characters did not know the main characters (and the opposite). Well, just decided to change that so it makes more sense.

I decided to create a discord server anyways. Join for more bonus teasers, for any questions you may have or to join the team and help improve the game! (link updated)
