I don't normally write reviews, especially so soon after a game releases, but I feel like this game deserves one. I've just been playing through the prologue and I can already say that the horror aspects were done so well. I'm not one to get easily disturbed, but some of the scenes were truly unsettling. As someone who plays a lot of similar games this one stands out. I definitely recommend trying it out. The story itself is so captivating and so is the world and character designs.

pretty fun turn base game. The art style is very nice and pretty. my only thing is the game puts you into the middle of an already "built team" at the very beginning. the characters are reacting to what's going on *trying to avoid spoiling* with pretty strong emotions, but I have no idea who they are or why anyone is important to react to the early cutscene. after a few missions and cutscene it makes a little more sense but still building the familiarity with the story characters. still great 👍

The card battle system is interesting once you get used to it. The gacha system is the typical stingy 50/50 pity but most characters work regardless of star level. The game also has too many different currencies. The story also feels slow. Typically, prologues do something major to draw you in early, but Im 10 hours in at ch 3 and still nothing. The premise has potential. The art, music, and graphics are really nice, but the game does not offer English dub and fails to translate all dialog.
