Morefuyu (otherwise known as Morenatsu 2017 Christmas Special) is a non-canon fan continuation that's currently in the early stages of development.
The game is set around 4 months after Morenatsu, with Hiroyuki Nishimura returning to Waterfront Village to spend his winter break with his friends. Currently, the game is in the early stages of development and no routes have been released. Developers have stated that alternate endings will be added to the game, but only after each character's main route has been finished. The current development team consists of a total of 11 members. The game is being developed in Ren'Py.
