"Chess Marathon" Game

You begin as one lonely pawn on a giant chessboard that stretches 1,000 ranks long — your mission is to climb all the way to the top! Every time you move, black makes a real chess move right back, and the squares behind you crumble and vanish. Here's the fun part: capture a piece and you turn into it! Grab a knight to leap over obstacles, snatch a rook to slide across the board, and reach a gold rank to transform into a mighty queen. It's the chess you know, turned into a speedy, heart-pounding race!
