I think you've definitely got something very special here, and this seems to be the champion of siren head games.
Unfortunately I stumbled across a game breaking bug towards the end. This soured my experience, but I still think that this game has some very strong qualities.
My biggest criticism is the filter. I understand that it's part of the aesthetic, but I couldn't tell what I was looking at half the time. On that basis, I think it might be worth toning it down where possible.
