Sonic.EXE Phantom Corruption
4 days ago

MERRY CHRISTMAS EVERYONE! I hope all of you are having a great time with your loved ones this special day.

So, since I dont have a special gift for Christmas, I decided to make a devlog post reporting the entire game's current progress. Read the article:


In addition, I want to thank everyone who supported me and project... especially those who volunteered to help with its development! It means a lot to me and I truly appreciate it!

1: GAME PROGRESS OVERALL

(Note: Corrupted Sonic's sprite here is outdated...)

So, by observing this image you can understand the condition in which every route is in at the moment. The colors also have meanings:

BLUE = Route finished, no changes are expected atm/changes done

GREEN = Route finished, changes will be done

YELLOW = A step from getting finished, changes will be done

ORANGE = Not finished, changes may be done

RED = Not finished, progress temporarily paused

So, yeah... I think there is nothing more to explain here...

2: IMPROVEMENTS

Once again, all the existing frames are getting enhancements in order to make the game as fun and good-looking as possible. CHARACTER DESIGN & DIALOGUES ARE ALSO INCLUDED. The classic modgen design was great, but it feels way too overused now with the newest exe fangames, which ALL use them. So I decided to swap to MODERN modgen style, not just for that, but because I was intrigued from the design. What I have to do now is replace the old sprites with these and fix animations and other stuff... Also, the new textbox and text font will be way smoother than the old one + I can use small letters + I can add more text in 1 dialogue without getting off-limit. Finally, I will try to add decorations to some stages and improve the gameplay so it wont be too boring (mostly a couple more "challenging" paths)...

3: DEVELOPMENT PLANS

Currently, I am still fixing the sprites and making improvements, so progress is paused. It may take a while, but it is going to be worth it. Once they are done, I will get back to development, finishing everything I can while I'm waiting for the team to finish some sprites I need. Once the sprites are done, then there is nothing to stop me from finishing the game!

4: STORY PLOT & ENDINGS

As you may know, the game is divided into 2 parts/game builds (used to be 3).

At the moment, we are still on the 1st part of the story, which is just the beginning: How Sonic got corrupted... His friends realized what is happening... Chaos has just started to spread etc. There will be only 2 outcomes in part 1: BEST ENDING & WORST ENDING. Any solo/duo/trio/squad survivals will get a results screen. However, you still get to unlock the SIDE STORIES, which may give some additional content!

Part 2 comes after the events of part 1 best ending (obviously), with the heroes facing new challenges... [NO SPOILERS]... while at the same time they try to figure a way to stop the corruption and save Sonic. This part will include character development and much more... However, there will be actual endings for, if not all, then most possible outcomes.

I'm saying "most" because having 7+ playable characters means there can be TONS OF ENDING COMBINATIONS. I have ideas for spesific endings, which I will probably focus more on. So it can be extremely difficult to create 100+ ENDINGS... Most likely, some outcomes will have actual plot and stages, and some others just a couple of scenes. After all, it's still an outcome, just not an interesting one.

5: RELEASE DATES

I can't estimate a spesific time for when part 1 will be finished. Progress can be really weird for the few reasons I explained in old posts... Well... I failed to release part 1 this year, and I'm not even close to finishing it as you see (It's funny that I actually thought I would release a PART 2 DEMO AS WELL...). Don't worry though. Part 1 is definitely getting released in 2026 ("Wow thanks for telling us like we didn't know that-"), but I cant estimate which month or date. Hopefully I will complete it until summer (No promises... you know me... maybe-). That's all I can say for now.

6: NOTES

  • Considering if I should remove the "EXE" from the title since the corrupted Sonic is Sonic himself and not some kind of evil entity possessing him.

  • Thinking of a cool name for Corrupted Sonic. It won't be used in the game at all, but we can still use it to refer to him.

So, that's everything. I will still upload progress both on discord and gamejolt (I recommend discord because I post a lot more stuff there). See you all, have fun, and I wish you an amazing new year!!

History repeating itself, right @LiNX_4 ? XD

Just wanted to show Amy's continue screen before deleting it, since it was not included in the demo.

Basically, I will remove all continue screens and replace them with 1 for all characters, which will be made from scratch.

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

HELLº!!!!

Do yOU WANT tO PLªY WiTH the ALLFATHER?!????

Sonic, Tails, Knuckles, Eggman, Metal Sonic & Sally are getting a sprite replacement.

Progress will be temporarily paused until I finish with all sprite replacements and any other improvements.

Thanks to @Rushed_Account for Eggman's jetpack sprites!

Bros getting freaky

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.

Also progress update:

Sally's route was finished!

WIP lol

#UndertaleCharacter

Sans.

I don't think there is a reason not to like him-

Just a chill guy who somehow knows a lot about the player's actions (prob in a similar way as Flowey) and has some of the most touching lines in the game.
