Understandable. In that case, if would’ve been great to have a visual difference between prisoners, just to express that idea.
About the time limit, a timer would do wonders to let the player know what is going on.
And sorry, I totally forgot to congratulate you on my first comment and it only seems that I focused on the feedback, but congrats on submitting a game! It’s not an easy feat at all, and it’s great that you’re continuing your work after the game jam ends! Good luck with that!
