The writing and design was great, and I thought a lot of visual choices were cute. I'd like to see more from you, and some finer tuning it'll be wonderful. 
(Some example of finer tuning: Less fourth wall breaks unless the entire game from the beginning establishes that's the type of story it is
Easier to know how to get to the next plot point, unless you want the game to be open world, in which case add more things to do
Fixing some NPC dialogue to fit with the current moment (some new about the murder before it happened))
Loved your game thanks so much for sharing your talent!

Loved the music, the custom buildings, and the setting.  Reminds me of a Professor Layton game for some reason but it was a nice and short who dun it mystery.  A shame it was rather short.  I think it needs some finer tuning with the camera and people placement.  Would like to see this done on a bigger scale someday.  It was fun to play.
