If you enjoyed any of the metriodvania Castlevania's- especially SotN or Laiment- you will love this games's gameplay. It it isn't perfect though. I've stopped counting how many times this game has crashed on me, or times when I was unable to retrieve an item drop because of technical issues. Be ready to have a little bit of patience for this game. Also, make sure to eat well.
I wasted my money on this game on steam when it had come out on steam. This game wants you to think it is a horror game with its initial presentation. What it really is some liberal arts student's creative writing assignment brought to life in a walking simulator. Here is the plot in one sentience: Your lesbian sister ran off with her lover, and everyone went to find them. Is that worth the price of admission to you? Personally, I still want my money back.
