//* General Comments or Finished Tasks
//TODO Tasks left to be done for game
//! Bugs or Issues
//? Questions or Suggestions

//! Aftering hitting down with hammer, turning stops working in what direction the player tries to move first in
//! As with throwing objects, the rock sometimes goes in random directions and random speeds
//*TODO Playing StickBeating Game, player should be able to throw rocks every few seconds
//? Soft auto lock on enemies when throwing rocks
