Cool game,x spirit and x are the best.
Ok people,I'm going to help you a little with this,use password 1hr9 or 1hn9(I don't really remember how its typed I just know is one of those 2)So after that Pass the level that it takes you 4-1,you will be taken to 4-2 where you have to kill 100 enemies for X,then pass all the game with X without passwords to get X spirit(It may not happen,may get glitched but anyways)Thats how you get X!
