The Unfinished Swan, a classic PS3/PS4/Vita puzzle game about splashing paint around a barren environment, might be getting a follow-up. At least, that's what fans are speculating after a cryptic tweet from publisher Annapurna Interactive.

The Unfinished Swan was developed by Giant Sparrow, which went on to create What Remains of Edith Finch. The two games are explicitly connected, although explaining how would be a spoiler. Edith Finch was published by Annapurna Interactive, and the company has now tweeted out a picture of a paint splash from The Unfinished Swan.

You can see it below. Despite the image just consisting of a black paint splash, The Unfinished Swan's style was distinctive enough that we have no doubt it's a reference to that game.

The game was published by Sony, and was thus exclusive to PS3, PS4, and PS Vita. It could be that Annapurna has the rights to port the game to new systems; it could be that they have the rights to a sequel. While some have noted that the tweet was published from an iPhone, which could be a sign of a mobile port, it's worth noting that many of the account's tweets are made from the iPhone Twitter client.
