Hello.
I don't know what exactly you are referring to with the savegames, but the ideal is that you transfer your savegames to each update so you can follow your progress, in the past there were incompatibilities between the saves of each version, but that was because I added scripts to the game that created those incompatibilities.
But now I don't intend to add more scripts so I hope there will be no more problems in this regard.
Regarding the tentacle scenes, yes there will be more, but to be honest it cost me a lot to animate the scene of Eveline and the monster in the elevator (even if it was a simple animation). so I won't add more tentacle scenes until after a couple of updates.
And to finish, yes, if you open gangbang scenes, however I want Eveline's corruption to be gradual (although this also depends on the player's actions of course), so the "hardcore" scenes will come in a couple of months.
I hope I have solved your doubts, and thank you for following my project ;)
