HerrLeutnant - thank you! It is a rather complicated answer that I have for your question. If you're a familiar with the game mode of my Desideratum game, it will work like that. Inventory, items, maps, random fights, boss fights and such. However, my programmer and friend that was gutting and remaking the game mode from scratch has recently vanished.
He and I talked almost every day for a year but he suddenly went silent about a month ago and I worry COVID-19 or something has possibly hurt him. I am very hopeful that he will return! It is by the help of my programmer fans that I am able to do anything like that. So as of right now I am not sure when I will be able to implement the game mode. On the flip side, as with DBB the game mode would not kick in until chapter 4 because that makes the most sense.
If you'd like even more insight on my GN plans, I shall be releasing a video on April fool's Day! That will be on my YouTube channel, and I will likely put a link here when I upload it. It will go into more depth. I'm glad that you enjoyed this chapter one, and just know that there are so many more games for you to enjoy besides this one that I have finished!
EDIT: I had just woken when I answered you earlier, but yes, as with DBB there will be well over 100 Bad Ends, and some will have pregnancy and the multiple endings will work like my Cult of Corruption game with your choices leading to the game's end with the canonical ending, a supervillain Trixie ending, or a Trixie who is now a giggle girl end!
