Four Colors Update - Drag and Drop, Design Improvements, and More

The Four Colors game has been updated with a drag and drop feature for easier card movement. Cards are now displayed in a single line, removing the previous imitation of holding them in hand. The playing cards design has been updated by removing transparency, scale, and overflow effects to match other card games. The board style has also been updated for consistency. A new effect simulating 'lifting a card off the deck' has been added instead of moving the entire stack. Additionally, a bug that caused some played cards not to be removed from the hand has been fixed.
