For your first game, this was a fun ride - decent demo.
I accidently made myself laugh out loud during the first conversation and sort of set the tone for the whole video. The atmosphere is really bland. I can relate to that, because this is your first project. The mechanics were good, sometimes a bit janky. But, my personal suggestion is to work on sound design - wind blowing, maybe add rain, some outside car sounds, it would immerse the player more. Also, you can add a fan, that works inside of the building.
Overall, like I said, not a bad demo. Best of luck with the future games!
Just a small note - I would avoid adding famous movie character assets in your game, especially if you want to have a commercial success. Having original characters works better. Talking from experience.
