This was lots of fun!
I was quite happy when my "just swap all weapons clockwise" strat didn't work.
I actually had to pay attention to who was moving into which room.
For this sort of game, not being able to cheese it makes it more fun.
:)
The only 2 things I would suggest changing relate to the tutorial:
1) make it so that x+c resets the tutorial, rather than jumping you to the main game (I suspect you didn't have time in the jam); and
2) add, maybe, one more explanatory sentence that explicitly tells dumb dumbs like me that we are trying to prevent murders - at first I thought that I had a target of my own to kill.
