It's really good! I am immediately intrigued, and the style you employ in the visuals is amazing. Color-matching the characters' silhouettes with their dialogues are a good call. It helps me easily establish the people and that this is really focused on the personalities moving the story. There's definitely a lot you can do with this format moving forward.
The story was great so far. I'm not sure what you have in mind for it just yet, but admittedly the pacing in the confrontation between Eddy and the suspect was a bit too sudden for me. Then again, it's a demo, so I can forgive it, haha.
I wish I really could do more than be a passive reader. I can't help but want to reach through the screen, immerse myself in Eddy's world, and be more involved.
Overall, amazing work! Keep it up!
