Super great experience !
The only suggestion I would make is to teach the controls when you first approach a prisonner. When I played, I did not entered by the front door but by the west (because I like exploring) and so I walked around, reading messages and making my own mind on what's happening. After that, I came across the tutorial message telling you either help or kill the escapists. I thought it was too straigthforward, it directly tells you you'll have a choice to make and that already shapes your mind. So I think you should remove the 2 first messages and tell about what you can do only once you're in the situation. And maybe tell about the consequences of your acts just after your action.
