Why the release at this midnight (GMT) time would be the most appealing

[FredWP]

Because we would like to sleep and not worry about any of the things that can go wrong when a game is released to the masses. So better to release the game when we are awake and peachy, ready to assist and fix any issues there might be!

For a horror game developer you seem to be pretty frightened of the night, wanting to sleep all the way through it. :p
