Awesome stuff, thanks for taking the time to comment :3 I'm happy to give you some hints or straight up tell you how to get those few ends that you're missing if you decide you need a hand! Just drop me an email here and I'll get back to ya as fast as I can: solipsismreigns@gmail.com
SPOILERS BELOW HERE ALSO
Hehe, I don't know if you'll care about the originals more when you get the true end or not x3 For me, I care more about 339 and 13/Dollmaker! They're kinda like the best couple to me, even though they're technically not the true versions.
As for Kuro throughout the different routes, I didn't actually ever say for certain if it's the same one, how much he remembers, etc. I kinda just left it up to whatever the reader wants to believe. In my head, it was the same one, and he remembers quite a bit, but is powerless to do anything about it, so he's slowly driven insane over time (which is why he sometimes goes yandere, haha.) It's kinda like in each new world, he's sorta refreshed, but he has much more awareness than the protagonist. In a way, his suffering is worse, cos he's forced to remember more. A part of me wanted to write that the first Kuro you meet as 26 in the ??? route (the one who you kill to set free in the white room) is the 'real' version of the Kuro from all of the other routes, but I decided not to in the end. As I said though, I didn't actually explain that in the story cos I wanted the reader to interpret whatever they like :3
As for the guy who calls you Anathema, I can't say too much cos I don't wanna accidentally spoil anything for you >.< haha. But what I will say is, more is revealed about him once you reach the true end :3 I'm so glad that you tried entering your name as Anathema though, because there is actually a small easter egg for doing that :D It's not much, just a slight difference in dialogue, but again, I won't say more, cos you'll only find it when you get the true end :3 Basically, there is a scene, and if you have your name as Anathema, it just changes one line in that scene as a teeny tiny easter egg, haha. You actually lose a choice if your name is Anathema though, it gets skipped and replaced by a different line, where normally there is a dialogue choice if your name is anything but Anathema.
Thanks so much for playing and commenting :3 Good luck with getting those last endings! And like I said, feel free to drop me an email if you decide you want some help ^_^
