Luna Child no Saishuu Bouei Line 3

Luna Child no Saishuu Bouei Line 3 is a five-stage Touhou Project danmaku shooter by ENAMEL SWORD, first published as version 0.50 in May 2015 and finished as version 1.00 on 10 December 2017; the circle presents it as a side story to its own Three Fairies RPG and as a Touhou reworking of its original shooter ISD!!. Unlike the fixed-screen second game it is a vertically scrolling shooter played in a tall portrait playfield, with a focus key for slow movement, a marker showing the boss's horizontal position, and item auto-collection when the player flies to the top of the screen. Its central system is the LUNAR meter, which doubles as shot power and as a shield: at 999 or more a hit is cancelled and every enemy and bullet on screen is erased for half the meter, and the player can trigger the same effect manually for a third of it. A dynamic rank speeds enemy bullets up the longer the player survives, so the manual recommends spending the shield deliberately to hold rank down.
