DDLC is an awesome game, and as much as I like it, it would be pretty cool if the game had 2 modes:

-This one (classic) Where Monika is aware that this is all a game

-Normal- Where the characters aren't aware that this is a game. That would really alter the story and maybe add more endings?

What do you think? 

Now, this would probably require a lot of work  so if you do want to update it, take your time.

Sadly, it is unlikely that this game will be updated because according to MatPat's videos this is just a sequel to a new game by Team Salvato that is coming this year.Apparently, it is a prequel of this game.

Is that true?

If it is, that is the best advertisement method I've ever seen!

Fun Fact: When I installed the files from DDLC on my phone I got several new pictures in my gallery.Two of them really stood out.They were shadows of a boy and a girl.The boy might be the protagonist, but the girl doesn't resemble any character from the game.

I would love an update (even if it is in the form of paid DLC) where it added in that "Normal" mode. I would think it would be best to unlock it after completing the "Classic" mode. Normal would then play out how the game would be if Monika didn't do what Monika did, and like you said, none of the characters are aware of the fourth wall, at all.

Also if I find out anything more I will update the topic.
