Fresh Animations: Player Extension + Just Expressions

• Fixed missing variable names for random eye movements (twitching, looking around).

If you prefer the eyes to only look in the direction of the player's gaze (without unnecessary movements), then stay on version 1.1.

• Updated pack.png;
• Fixed an issue where animated eyes did not appear on version 1.21.4 (and possibly some other versions).

• Textures have been removed cuz they are already included in the dependencies.
