****Major spoilers to this game***
There was originally going to be a route where you side with Boumedian (the old man) but it was scraped because the ending would have been the same and the game was taking too long to finish anyway. Yes, the game between ''existence'' and ''milker'' will have more lore about the T's ( But the T's are already explained in ''Happiness 2' and ''A Happiness story''), and it will explore Eva's identity ( Alltough it's pretty obvious if you played ''A Happiness Story''), the knight identity ( again it's pretty obvious if you played '' A Happiness story'') and finally CC's identity ( which is not obvious yet). The MC powers need more explaining but you can kinda guess from what happened in ''A happiness story''.
Finally, even though this game currently has fewer views and downloads than games like ''Milker'' and ''Null'' I still consider it my personal favorite project. I know everyone likes''Null'' and it is currently very well received and rated but ''Existence'' to me is something else. It nearly drove me insane working on it for 2 years but getting to write about political fiction was very fun and seeing the characters move around and interact was super cool to me.
