oh i loooove those types of games! and there isn't a really great free (other than AGS, which is a little dated) option for making them right now so honestly a VN is a great way to scope down an adventure game while still retaining the overall design! i love the premise so far, and i feel like it definitely could have multiple interpretations of the "cold" theme too, so i'm really interested in seeing your characters. best of luck with the jam!
