D.

You play as Sami, a doctor on his first day, moving room to room to sit with the patients and help them. But soon you notice that every one of them is hiding something, and the curiosity is killing you, so you start looking at places in the hospital that you would rather leave alone.
Then the radio the receptionist handed you starts turning on by itself. You tune it and it opens rooms that can't be opened, and you start to question what's happening with this place.
But don't forget this isn't what you came here to do. You still have patients to sit with, and the details you record from those conversations are what let you take this hospital apart. Just know that something in here has noticed you, and it's trying to stop you.
This is D., a 2D puzzle and mystery game set in a psychiatric hospital where you investigate the hospital and its secrets.
How it plays. Every session is a conversation you steer you pick what to ask, and words turn into topics once you know enough to ask about them. Everything you learn pins itself to your clipboard, and connecting the right notes together is how you reach conclusions the game never states out loud. Connect the wrong ones and it only tells you how many are wrong, never which.
The radio. A dial from 530 to 1700. Some signals find you, and others hide from you they only exist if you land almost exactly on them. Tune it right and rooms open that couldn't be opened.
And this hospital could kill you. Some places aren't safe, so you'll need to hold your breath, and it only buys you a few seconds. Get cut and you'll bleed. When you die, the clipboard writes down the time and ticks the cause.
