This was a fun little entry. I've struggled with making good detective-style games, so I can appreciate the challenge of making something that really pushes the deductive skills.
Elementary is a neat concept and a fitting alternative to turn-based combat for the setting, even if it's odd enough that the characters remark on it.
I loved the modded busts and character sprites. The maps look great too, very nice use of the RTP.
The very not-RTP music is fitting for the setting.
Overall, I enjoyed this clever twist on "Clue in RPG Maker."
