It was all a misunderstanding that arose on Discord, with regards to this latest version of the game. Hence the mention of a "surprise" on the main page here.
The surprise itself had nothing to do with the game per se but it was to do with the relationship options with regards to Caroline in this update and the optional paths branch system at the end of it.
So if people have now played through to the end of this version then they'll see it. It's down to them as to whether it's a surprise or not. Icstor has never said that there's a surprise in this update.
When I heard about this, I was actually looking for something else in the game with regards to the so called "surprise" and when I completed this version and saw the ending, it was like "ooh choices, that's nice"
So not really a surprise as such for me, considering the script in previous updates of the game and some comments in the game along with the comments (cum inside me, don't cum inside me) when in bed with the MC, then it was surely on the cards for the options to be put in the game.
So overall not really a surprise but more like game branch options with the women in the game.
