Nice concept! I love murder mystery, detective stuff, and hunting for clues to reveal the whole story is always fun for me. I liked that you highlighted the things which can be searched, although perhaps that made it a bit too easy. Not sure if it was just me, but the camera consistently drifted to the right even when I wasn't moving, so I would recommend looking into that for any future updates/projects. Overall, though, good job! You can definitely take this prototype and expand it into a nice investigation game. :)
