The Last Ninja Beta Fixes/Changes

Based on feedback from some amazing testers a few things have been changed/fixed. 

Changes / Bug Fixes:

• Game instructions/rules added: “Kill 10 zombies, to face the boss and collect the treasure!”
• A barrier has been added to encourage the player to kill enemies before progressing to the boss, 10 kills will cause the barrier to fade.
• Health now flashes when taking damage, thank you Joel for pointing out its hard to notice (JD).
• Boss now respawns after resetting game, thank you Andrew (AL) for spotting this.
• Player health is increased instead of just visual after eating food, aka global health value has been fixed. (AL)
• Volume has been lowered and music can be paused with “P” and resumed with “O”
• “Score” has been replaced with “Coins”, would like to add something to spend coins on in the future.
• When the treasure is collected, remaining enemies will die which will prevent the player from dying after the game is already won.
