Atmosphere is great and I love the art style, its very fitting. Battle system is fun as well, full mouse control for the bullet-hell sections feels great. Something of note that I really adore as well is the world building, I love how you can catch glimpses into the lore through the ghosts' dialogue, for example, they often mention "the basement" but it isn't really told to you why exactly, it's very fun and intriguing trying to piece everything together. Super cool game, very much enjoyed my time with it
