Changes:

• Playing instruments or listening to radio will restore "mental" stat.
• Cassette Player now works, but not as a casette player, but radio. Portable, hands-free mental stat restoration.
  • P - toggle player
  • [ - previous track
  • ] - next track (random)
• Listening to music near a fire will increase the rate of mental stat gain.
• Killing enemy bots will reduce your mental stat (-15).
• When playing an instrument or having Cassette player turned on, enemies will hear you from further away than running (150% range of running)

(optional) Mod Configuration Menu defaults:

• Mental penalty for kills: 15
• Radio (portable and stationary) mental gain: 1 per 6 seconds
• Guitar mental gain: 1 per 4 seconds
• Harmonica mental gain: 1 per 10 seconds
• Keybinds for Cassette player

For reference, being near a fire will restore mental stat at a rate of 1 per 4 seconds. With the music buff, this increases to 1 per 2.5 seconds.

Compatibility

• Oldman's Immersive Overhaul - Mental penalty for killing won't work (and maybe hearing of you playing, didn't test that). Rest of the stuff seems to be OK. Might require patches on my side in case of some major changes to Immersive Overhaul (I have a compatibility patch in my mod).
