Apologies for the end cutscene bug, that'll be fixed the instant itch allows me to upload a new version (after the jam judging is complete)
The last clue is inside, at the scene of the crime.
Thanks for playing, and for the nice comments!
Ah okay, you couldn't enter any houses so I didn't try to enter into the house you start out at either. Maybe that could be signposted differently? Like a glowing door, I dunno.
