Interesting idea for a puzzle game, beautiful artwork!
I didn't pick up initially still that I was making one cake for everyone vs. cakes per individual. It'd be nice to have a try again at the end to go back to cake making mode and retain your notes or even go back to the interviews. Agree with @MaybeAGhxst that the icons for the notepad were tiny, would be nice if that were larger, it was hard to tell what a few the symbols represented and what they were supposed to align to in the dialogue. (Also, the notepad covers the submission button on the cake screen, maybe move that to another corner?)
