Nice work, I like noir-esque art style and tone. Interesting mechanics to the game and a nice complimentary choice in music
If you update the game after the jam, I didn't realise at first that you could switch suspects maybe add line of text or a highlight button when hovering over the names to show that there clickable.
I would also suggest adding a prompt ingame on which key it is to interact with items.
I found the movement a little tricky at first.
The head focusing on the items was a really nice touch, the start screen is really cool and the character portraits have a unique style.
Great work! :)
