This is from the same company (Archosaur) that made Life Makeover. Meanwhile Papergames have the Nikki series.
I suppose they intend for this to be a direct competitor to Love and Deepspace, especially regarding the 3D graphics that a lot of fans have been screaming about.
As of now it is unclear whether the MC has a fixed gender, or if they will even let the MC appear in-game at all. So far seems very first-person.
Edit:
The game's Chinese name is 代号：神不言 in case anyone wants to check out their Chinese posts.
(Also this is my first post here, it slipped my mind that being stuck in moderation queue means there could've been duplicated posts. Oops...)
