From what I'm reading here, this game is an "unofficial entry in the Touhou Project" which is a "series recognized by the Guinness World Records as the 'most prolific fan-made shooter series'."
In the otherworldly realm of Gensokyo, a mysterious evil emanates from Scarlet Devil Manor. Investigate the source of this dark power as the Touhou Project’s principal protagonist Reimu while evading deadly barrages of bullets and blasting enemy youkai into oblivion.
Unlock new playable characters, Marisa and Cirno, to experience Azure Reflections from a fresh perspective with their distinct attributes and special abilities. Spend currency earned during each run to upgrade the girls’ skills with adorable stat-boosting accessories, including everything from bunny ears and devil wings to shoes, masks, eyewear, mustaches and more.
Put the gear to good use by harnessing increased speed, smaller hitboxes, an expanded pickup radius and other handy powers to better weave through complex patterns of bullets, run up the leaderboards and perhaps even perfect the game’s boss battles to see the story’s true ending.
