Ok first start under easy beat the first level and save then quit then start under normal then beat the first level and save and quit then start under hard and save and quit.(dont save all under the same profile...
Make three diferend ones...for all you stupid people out there) then go to the start menu and enter level select(U,D,L,R,L,L,R,R)and select easy and play level 23"the end of the world" and beat it then save then select normal and play level 23"the end of the world"and beat it then then save then select hard and play level 23"the end of the world".
Beat it then save(save under the games you started for easy,normal,and hard)(corect me if I'm wrong about the name of level 23) then start playing(level select,one of the three profiles,or start a new game)and enter the complete encyclopedia cheat(U,D,L,R,L,D,R,U) and all comics cheat(U,D,L,R,R,L,L,U) and you have beat the game.
P.S. Does anyone have a cheat to complete the consepte gallery.
