This looks awesome, really like the concept!
Visuals are great too and there's a lot of elements to the gameplay.
I had some strange issues tho and couldn't progress sadly.
Told a NPC to open their locked door, but they kept walking to an already opened door instead.
Then later on I decided to arrest them due to a possible weapon I found, but when telling them things like "You are under arrest!" they would walk to the open door again every time.
I wanted to see if I was right so I tried arresting anyone else to get to the ending. 2 of the NPCs kept on giving me their ID every time I tried. The last one just went "No, that's insane, I'm innocent" and nothing happened. But when I click the handcuffs it says I should interact with an NPC instead, so I assume you are supposed to tell them they are under arrest?
Also, one thing that could be an issue for the investigating is that I'm pretty sure multiple NPCs kept on lying (or contradicting themselves), so innocent NPCs lie too.
