So it appears the player auto-attacks whenever they're near any NPC, not sure if that was to demonstrate the character's increasing zombie tendencies but I liked that aspect either way.
Thats it!! We try do this, but we run out of time xD
It was meant to have a HUD that would show how close he was to becoming a zombie. And depending on how the HUD was, he would or not have control over his attacks.
And thanks for enjoying our game, we really enjoyed it!
