Monika states in Act 3 during her conversation with the player that Sayori's hands are bloody because her hanging did not kill her instantly, having stepped from a chair instead of a higher place, the latter which would have made her death quick and painless. The 'New Game' option will also be replaced with a line of glitched and distorted text, but its functionality remains the same.
