The most realistic story I have encountered in Ectocomp, Duck Diary is all the more scary for it. Dealing with anxiety and trauma, the protagonist finds comfort in a rubber duck that keeps them company through baths and through dreams. As a choice IF, it does not appear to be properly branching. Rather, the choices affect only the next screen. As such, you get one narrative, but with some variations in the details. The writing is of course the essence here, and it’s positively superb, mixing the realistic melancholy with touches of comforting humour provided by your rubbery friend, and a gradually unveiling horror that builds up as the story unfolds.
