Maybe the choices can still lead to bad endings, or choices that are aparently good routes but after a long travel it is a bad ending(but still provide extra information/lore), and you need to look for the specific route to get the true ending(much like in Happiness 2, "butterfly", "Null" and "Reeva")
It was my favourite part from "null", "zero-one" and "reeva", while doing a ton of saves for each choice lol. I think the slow progress from "Zero-one" played a bad trick on it, but i still liked it, it makes them more interactive i believe.
Btw didn't CC had her witch powers from "existence"?, also i think "existence CC" is pretty different to the other CCs, or it is bc cronologically she existed first in "Existence", then she became self-conscious
I think Destiny was kinda overconfident that Alex did not have his powers charged, she could have gone with a small army or 4-5 nulls to help her
Also i think there was a plot hole, Alex was the one that didn't tell Carmine where he was going(in the "Existence" flashbacks), while young MC was the one that said goodbye to Carmine and to wait for him, but Alex was the one that reencountered with Carmine, in "Carmine" game. Or am i wrong.
Also didn't reply this on "Carmine" but sad to not see Hassan there lol.
