If I was going by raw math it'd be 3.5 stars, rounding up because the good bits are REALLY good. Loses .5 stars for making me take notes in an external app to get the true ending and a full star for having entirely too many major glitches for a VN (multiple instances where I ran into loops where the same day would repeat multiple times and Salxire's route was weirdly prone to failing to find backgrounds).
