Dear Space

In a resource-depleted future, the Earth Federation operates massive "Planet Cracker" starships to harvest asteroids for survival. The protagonist, Euclid, a skilled spaceship engineer and former security officer, is sent to repair the internal tram system aboard the colossal mining vessel "Stone Virrage" at the request of his lover, Crow. Upon arrival, he discovers the ship has been overrun by grotesque monsters—humans, creatures, and machines all corrupted by a mysterious substance called "EX Cells" that drives them to replicate and attack indiscriminately. To Euclid's horror, Crow has become "Mother," the first and most powerful infected, now commanding a cadre of specially mutated women known as "Monmusu." Armed with the "Prototype Wave Cannon Type R"—the only weapon capable of neutralizing EX Cells and restoring sanity—Euclid must navigate the claustrophobic, hostile corridors of the derelict vessel. Each Monmusu presents a unique challenge, from former security personnel and crew officers to researchers, each transformed with distinct abilities and powers. The game is a shooting action-RPG that radically extends RPG Maker MZ's capabilities with extensive plugins, delivering a hybrid of combat and narrative. Victory against bosses grants new skills and abilities. Defeat triggers intimate "defeat recollection" scenes where bosses attempt to overpower the protagonist—the stakes are brutally personal. Euclid must restore the crew's humanity and uncover the truth behind the infection, or be consumed by the very people he came to save.
