The game is a horror exploration puzzle adventure played from a selfie perspective: the player controls a girl who films herself continuously with a camera, so her own figure and whatever stands behind her fill the screen while her front stays out of view. A demo is available now on Steam, where the game is priced at 1,300 yen. A Nintendo Switch version is also planned through Wakuwaku Games. The setting is a world once sustained by an energy called Magenta Heart, which mimicked physical phenomena forever, then turned cyan and began turning anything with form cyan as well, driving living things and machines mad. The girl enters an abandoned facility rumored to hold something that stops that erosion and works toward the deepest part.","whyItMatters":"Sio is a university student majoring in design whose first Steam release was the 2021 title Tatarian aster, and he has said he kept the selfie camera because he wanted the act of taking selfies to carry meaning in the story.","webCardHtml":"\u003cp\u003e\u003c/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eShoei Sio\u003c/strong\u003e is a university student majoring in design.
