Patch 1.0.4

I fixed a few bugs.

• Fixed a bug that HP bar shows a negative health point when a player die
• Fixed a bug that a locked warning popup in the character choice scene cannot be closed by a controller
• Fixed a bug that a item key tag say "LT" not "LB"
• Fixed a bug that a item key tag does not disappear if a player enters again the position of the item after he/she gets it.

I make Nemo Dungeon a little easy.

• Increase the cool time of machine gunner who have a red head.
• Fixed some map enemy arrangements.
