Really cute! I'm sure everyone was screaming about the very end, but the tonal whiplash from the Department Head's letter to Harry and Hawley's reactions, with that music, had me in stitches. Not to mention the knowing looks they were giving each other over the insults, ahhhh. 

The format is also extremely cool, this is definitely one of those visual novels that make me go 'I should make a visual novel! I want to create a thing like that!' It's very short and well worth every minute of your time it requests, with two really developed leads and a world that gives the impression of being broad and well-developed, even if we see little of it in the end.
