# Script: One-Man Duel Battlesystem                                            #
# Version: v1.03                                                               #
# Install: Press F11 and place the Script directly above [Main].               #
# Description: This script allows for a timed-based battlesytem which works    #
#              only correctly with 1 party member. For a very nice experience  #
#              make the Battler with an over-the-shoulder perspective.         #
