Cancelled project utilizing the Morenatsu ~Revisited~ Open Source code to create a route for Mr. Amaki.

Morenatsu expansion focused on Torahiko utilizing the Morenatsu ~Revisited~ Open Source code. The project included new art cgs and would cover several events including visiting a swimsuit store, a swimming competition, birthday party, and college entrance exams. 

Intended as a sequel to Morenatsu. The player returns back to Minasato village another summer vacation with most characters now in their senior year of high school. Appears to have a premise of helping the characters choose their futures along with the similar premise of Morenatsu of the chance to grow romantically closer with one of the characters.

Originally titled 'Morenatsu Revitalization Project 2015' and later 'Morenatsu Project' this project was an attempt to continue development of the original Morenatsu within RenPy. It would later be finally named 'Morenatsu Revival Port', a faithful remake of Morenatsu in RenPy to preserve the game and make it easier to run on modern hardware. It was finally completed thanks to the efforts of their final member, RtlStien. The team was originally called the Morenatsu Revival Dev Team before being renamed to the MP team.

A remake of Morenatsu that was meant to be funded through Patreon donations that ended up being cancelled.

Morenatsu: Lost Days was meant to be a continuation of Morenatsu starting from the camping trip. The project had the goal to be as faithful to the original game while being made in the RenPy engine with a goal of 30,000 words for each route. The project was also planned to include new art.
