This prevents animation from freezing for the remaining player • Fix! Critical GUI freeze bug when players press ESCAPE during animation • Fix! GUI not closing properly after animation completes - GUI now closes automatically after showing winner for 3 seconds • Optimize! Game now runs in background mode - closing GUI does NOT stop the game.
