Since this is based on real life, I think you should be ashamed of yourself that you actually used glue traps (and actually recorded their pain via sound). There are far more effective and humane way to remove rodents ... do you honestly think that any animal deseves to die of starvation, shock, chewing its own limbs, getting its eyes stuck, etc from an intentional human action? It's akin to torture, and these kind of traps should be illegal.
I suggest you go read Tom Fulp's article on these kind of traps. Yes, mice can be pests but that is no excuse torturing them. And using glue traps does exactly that.
It's funny how the UK is banning fox hunting, and animal protection societies frown upon snare traps but no, glue traps, which are the worst you could do to a living thing, are actually legal in the US. Living hypocrites, and if you truly believe that unnecessary cruelty and animal torture is wrong, then you shouldn't be using glue traps.
Ah no but they are "only mice" so I guess it's OK? I am sorry I'm being harsh, but what distrubed me the most that you actually RECORDED the sounds they made when they were in agony. That's the kicker.
If this game was not based on real life (and the methods you used were actually acceptable) I would've gave it a higher score. But you are recommending glue traps, and I can't believe any person with compassion and respect to life would use shuch disgusting devices.
