Entwined is a rhythm game developed by PixelOpus, a studio which consists of former game design students and is part of SCE Worldwide Studios, for the PlayStation 4, PlayStation 3 and PlayStation Vita. The game was announced at Sony's E3 media briefing on June 9, 2014 and was released worldwide on the PlayStation Store for the PlayStation 4 on the same day. The PlayStation 3 and PlayStation Vita version were released approximately a month later, and since Entwined is a cross-buy title, these two versions are available at no extra cost for anyone who has purchased the PlayStation 4 version.
The player is tasked with guiding the two souls simultaneously, one with each analog stick, to bring them together over the course of many lifetimes. The left analog stick controls the fish, while the right analog stick controls the bird.
