The glich is that when you first enter the room with the gaint sky cannon near the end of the game and if you save before talking to the guy there to get him out of the room so you can warp the cannon elsewhere without being seen, the game gliches and when you restart the game at the save you start at the cannon room but the guy wont be their because the game saved with him standing where he was before you first entered the room but the game acts as if he was still there. This leave you unable to leave without talking to him or warp out cause the game thinks he's can see you but it's impossible to talk to him because he not there and there not way to reach him...
