It is a Fan-Comic that the event takes the place after
Five Nights at Sonic's Maniac Mania in different timeline (dimension)
and it is based on the Games:

FNaS Maniac Mania (The Characters),

Sonic Forces (The Protagonist "Avatar" and some Mechanics),

FNaF Security Breach (The Roaming Mode and
"the posibility off sitting in the Office Room" and
some other hidden things to be revealed in future).

If I could, I would make a Fan-Game... but there is a problem.

Firstly: I'm not a Developer (Can't create a Game).
Only a one person who's working with the Comic, that at least this one Comic... Exist.
And I'm not going to involve people, because...
Oh mother! How much work would it be to make a Fan-Game.

Secondly: The Project has been reset from the Beginning.
I have to start all over again, because the plot has been drastically changed and
in the meantime... I will be making drawings in which the action takes the place.
(The previous version of the Comic did not have a course of events before
the Main Story Mode started, now it has.
So, I have to do everything chronologically...)

And thirdly: Not all Characters are yet completed.
And I'm not only dealing with 5 Characters
(Sonic, Mario, Yoshi, Tails and Golden Sonic)
but... with all the Characters from the Maniac Mania series
Plus... Characters from Fiercy Forces...
so please understand my situation. Thank you.

And fourth: Why is "What If" in the name?
It is simply a "memento" of what this Project has started with.
As the prototype known before as:
Five Nights at Sonic's Maniac Mania "What If"
(After renaming after a year, because the plot has changed drastically, etc.)

I hope it will clears up what I have said.

Now, if ya excuse me, I gotta go now.
Thanks for the attention.
