Every time I see an update for Kodoku, I want to partially look away. Not because it looks bad, mind, it's just filled with incredibly creepy imagery. For months we've been looking at stills in a mostly visual novel-like sense, but now we have a solid idea of what gameplay is going to look like with a new work-in-progress video.
It looks like an adventure-like affair, with a heavy emphasis on the manipulation of light. Despite the low-key engine it does seem sufficiently creepy. Kodoku will make its way to the PS4 and Vita at some point.
