In short: I love this game, but...
First of all, graphics, animations, backgrounds... all that visual stuff is amazing. I felt in love at first sight. It's brilliant.
Music is pretty good too, my favourite pieces are: pretty dramatic LUCA rule and arabic-like Forest Foregone. Oh, those quarter tones...
I have to say that entry threshold is low. It's good for beginners who want to try the metroidvania genre.
Ye-e-e-e.... But... After 20 hours it turns out into a bloody dark souls. No. I'm not joking, this game literally raped me and then said "Hah, git gud".
I like it and sometimes I hate it. Strange feelings.
