Firstly, fantastic game, I really love the art and the setting, the fact that many hints and clues are scattered across different paths makes it possible to re-play a lot of times.
The question now is...who is the killer?
Spoilers below this point!
The corpse is completely burnt and Tomas' calls were cut short many times... My guess is that Spear is not dead but is either hiding or is an accomplice of the real killer. Of course the MC is hiding something but that burnt corpse might Tomas' maybe. Who did that and why? The MC seems to be friends with Tomas'... I love this mystery plot!
It seems the next chapter will be a continuation of the prologue, where the MC will either accept their "endless night" or save guys here and there, look forward to that, thanks for your amazing work, Ryu!
And you...who do you think is the killer?
