Cool game! The light/colour/phone thing felt like it was going somewhere but I couldn't figure it out, not sure if that part got finished or not. Overall, a bit clunky in the UI which I think made it harder to figure out what was going on and what I needed to do, but I liked looking around and exploring the place. The notebook and phone parts of the UI were cool.
It seemed like I went out of the office and was directly in the crime scene, so you could add a transition between them (could be a quick cut scene) to make it clear where you are.
The humour is good. The acting was better than most indie games, but I personally prefer no spoken words in indie games because it tends to mess with the immersion unless it's top-notch paid actors. I think if you keep at it and help to get the player immersed in the game with the visuals and clear instructions, then it could all work well. Hope you can keep working on it and finish it!
