Your game feels very polished and complete!
The core premise of your game is pretty good.
I recognized pretty late that I get a time penalty for destroying the wrong evidence so I lost that round pretty quickly and I was a bit annoyed I had to restart from the detective stage again. As that phase is basically no pressure and a good introductory point, it felt like a waste of time replaying again. A checkpoint for the thief-part would be a very worthwhile addition imo.
The map is a bit too large for my taste, but on the other hand you did a good job creating this large space with limited art assets and time budget which is impressive on its own.
You did a great job creating characters that fit the style of the environment art pack you used. Everything looks as if it was all from the same artist.
