so this has happened twice now, it happened my first play thru and stopped my game so I restarted and then i happened again. when i get thru the final door and the neighbor starts to chase me I understand youre supposed to run until you reach a door you cant go thru. however i cant make it more than 2 sec without him catching me! i dont kjow what im supposed to do if restarting it didnt work. ive tried running away dozens of times and i never last more than 2 seconds, i cant even get round the first corner. Is this normal? am i missing something? help!
