Provide audio effects

[bitbrain]

We require the following audio effects:

Music tracks:

• Game Over Theme - Dark, Evil, Slow
• Escaped Theme - should not sound happy (because the game is set in a dark, dense theme) but maybe melancholic again. I want to add an epilog after successful escape/failed escape
• Main Menu Theme - Calm, Melancholic, Sad
• Intro Theme - Calm, Melancholic, Sad, Piano (similar to main menu theme)
• Tension Theme - Someone is chased - Bass, Score, Fast, Run for your life

Sound effects:

• various monster screams
• monster footstep (similar to Diablo maybe?)
• open letter
• close letter
• game over sound effect (hall and bass effect)
• escape sound effect (similar to game over theme but with drums)
• press button sound (similar to GTA2 menu sound)
