I can tell you have a nice thing going on here.  The music and the atmosphere are really nice.  The music going faint in the crime scene room reminded me of old Sierra point-and-click adventure games such as Laura Bow.  You really know how to set a mood.

I have to be honest though, I tried to play the game twice and ended up stuck in what I presume to be a glitch, and fairly early on.   When I clicked on the furniture in the crime scene room, the menu went beyond the boundaries and I couldn't choose "ignore," which forced me in place.  This really hurts the experience as I really wanted to continue through to the end!

I wonder if enabling fullscreen mode would be enough to remedy it, some way to back out of a menu without having to click "ignore," or finding some static location with which menus generate as opposed to being relative to the mouse click.  The mouse to object collisions were also off.  Not sure if this is the experience for every player, but worth looking into.

A bit more polish and this will be a solid work!
