There's some good voice acting and an interesting story here, but the gameplay is a complete let down. It's essentially an on-rails very light 'puzzle' game about creating paths of light between hordes of rats, but we didn't find any challenge at all in it. There's also a rather unnecessary crafting system which seems pretty much ripped off The Last of Us, but combat upgrades really have no place in a walking simulator like this. The stealth mechanics are laughably bad, with guards shouting WHO MADE THAT NOISE and abandoning their post to investigate.
