Create the logic for a 2D match-3 game swap mechanic: When two adjacent pieces are swapped, save their original positions. Perform the swap visually. Check if the swap creates a valid match (3 or more identical pieces in a row or column). If a valid match exists, keep the swap and remove matched pieces. If no valid match, smoothly move the pieces back to their original positions. Ensure the player clearly sees the swap and the rollback if invalid. No special pieces or power-ups needed now, just basic swap and match logic with rollback.

Design the logic for a 2D match-3 puzzle game where players swap two adjacent game pieces (e.g., candies or balls). After swapping, the game should check if the move creates a valid match (three or more identical pieces in a row or column). If a valid match occurs, the swap remains permanent and matching pieces are cleared. If no valid match is found, the swapped pieces should smoothly return to their original positions, effectively undoing the move. Include these features in the prompt: Track the original positions of the two swapped pieces before moving. Perform the swap visually (with animation if possible). Implement a match detection function that verifies if the new board state contains valid matches. If no match is detected, animate the pieces back to their original spots. Ensure smooth user experience with proper timing so that players see the swap and the return if invalid. Support extensibility for adding special pieces or power-ups in the future.

Initial prompt

Create a simple 2D match-3 puzzle game where players swap adjacent colorful candies to make rows or columns of three or more identical candies. When matched, candies disappear, and new ones fall from the top to fill the empty spaces. The goal is to clear as many candies as possible within a limited number of moves. Keep the visuals bright and colorful with basic animations for swapping and matching. Include a score system that increases when players make matches. No complex power-ups or special candies at the start — just straightforward match-3 gameplay.
