Here's a full save file that was created partially on 1.6 and the newest version I could find, 1.7.
This game was unfortunately not bug tested very well.
(Skip to the end for the most important information if you just want the save as I expound on the journey required to create this)
Attempting to play through all 8 endings and fill out the entire gallery had to be done manually leading to many a headache. This was necessary due to save editors throwing an error because of some random out of bounds exceptions, thus causing the save file to be un-editable. The biggest issue for those interested was trying to get all the bandit scenes, as either the translation or game version 1.6 is glitched. No matter what pride Olivia had you would always get the version where she has low pride. This is intended to be the last scene in the progression but it will always play regardless of the pride value.
Additionally, I had to give the game several additional playthroughs because boundaries were not set correctly. Head Shop Kasai seems to have only anticipated people playing the game as he intended, leading to soft-locks or boundary breaks being possible in several locations. One such example is at the end of the bandit route. Right before you confront the Lord, you can go back into the recollection house and go to the recollection room, restarting the game. Because the game recognizes that Jed and Olivia's little sister are with her the game will restart with all three in the party. This switches Olivia's sprite to Jed's and causes other issues in subsequent playthroughs on top of just generally being not as attractive to look at.(Never thought I would appreciate the pixelated sprite boobs until they were gone.) Restarting would not fix this bug once it occurred.
I replayed through the entire game for the final scene I acquired after finding out this boundary break existed.
The reason I did not drop the completed save file with this boundary break performed is that it causes a soft-lock.
Said soft-lock occurs when you have Jed as your sprite and attempt to finish the blow phantom route. The transformation orb will not work correctly leading to being unable to finish the route. Therefore, I had to replay the longest route in the game for the scene where Olivia and Nord do not escape from the trapped house. This scene is excellent by the way if you enjoy the type of content this game aims for. Even with the chapter skips, because this scene occurs in the middle of a long sequence of events it took forever. Before anyone asks, no I did not play the game for 24 hours, my refresh rate caused that.
To those who are interested in the game's content and are only interested in the gallery, I feel you are doing yourself a disservice. A large portion of this game's atmosphere is contributed by the gameplay and small in game events that are not recorded in the gallery. Some examples are soloing the dungeon where Olivia has a hugger clinging to her face the entire time, losing to the final boss even after getting all your powers back causing her to have a mental breakdown, and watching Olivia lose levels to the tiny worms that should be insignificant contributing to her humiliation. While you will get an overall picture of the game through the gallery, you will not get the complete experience. I highly recommend that if you have any interest in the game you play through the majority of the routes on your own and fill in what you missed with the scenes from other routes.
You will enjoy this game very much if you can tolerate the MTL poetry and enjoy the following:
Humiliation, semi-permanent de-leveling of a strong protagonist, forced bodily transformation, forced changes in morals, and bukkake. This game is very unique in that the protagonist is aware of their mental process being forcibly changed due to the parasite. Several of the differing routes are based upon whether or not she is able to keep this desire in check or gives in to it of her own volition.
Most importantly, here is the answer to what is locked behind the eight endings. It is an incomplete area that will be finished in a later update. It is intended as an ending route where Olivia's primary corruptors are the Pigmen, as opposed to the other routes of parasites, bandits, and goblins. It is not finished, so don't expect anything to be there except for a teaser of what's to come.
Enjoy the save if you don't want to play through the entire game, but do be aware you are missing out despite the shitty quality control in some places. I enjoyed this game very much despite the issues. Please be aware that I did not extensively check to make sure every scene works on version 1.6. I know for a fact that these files work on 1.7 though.
