Just finished playing through all the endings. Really great story, Aspen is a delightful MC, and Crowe has just the right mix of Tsundere, cabin fever, and eccentricity.
I will say, though, the way the story was going, I felt like the Sweet Ending could've benefitted from a platonic (brother-sibling) love path as well as the love-love path. However, considering the VN's origins as a game jam game, how choices were likely made per that consideration, and that, based on how the story goes, if the Sweet Ending couldn't have two variants, just having that be a romance route, albeit a healthy one not involving deals with demons, I feel, was a good choice. Otherwise, if the Sweet Ending was platonic love only, then the only ending where Aspen actually romances Crowe would the one where they both become blood-bound psychopaths...and I get the distinct feeling from playing that this VN is not that kind of game!
