Love everything about this, addictive gameplay too! Awesome :)
One thing that could be changed is the weapon spawns. The key spawns all change every round (this is great) and the weapon spawns are in good places (some well hidden) but they don't change so once you know where they are you can easily get good weapons every round as a prisoner if you know how to get to them. So if they could also change like the keys but change to equally concealed spots
