Beating the final boss unlocks the other endings that can show up after that. I'm making sure that old saves work with newer versions so you should be able to copy the save file over.
Hi there, apologies for the necro. Love the game by the way, fantastic work.
I was wondering if you meant every ending, period? Just curious as the "Family Life" ending is still locked down for me. Got all the other ones, not a big deal really, just wondering is all. Curious if another playthrough is in order, hah. Thanks
There's a good ending for Anon and a "bad" ending for each antagonist. Getting one specific antagonist can be tricky so you unlock all of them when you get one of the the "bad" endings.
For Anon's pure ending you will need a new playthrough. However, I would say it's not worth the effort if you expect real vanilla content. It's mostly meant as a challenge.
