chess minigame in Unity with webGL

The chess piece rook will capture fruits on a 8x8 board, as soon as one of the fruits is captured, another fruit will spawn at a random location. There will be at all times 5 fruits on the board. There will be a timer for 30 seconds, player will receive different titles based on how many fruits they captured in 30 seconds: 3captues='baby rook', 6-amateur9veteran-12expert to 15='master rook' this prototype will first be developed with regular graphics that the freelancer will find himself, but as soon as the freelancer receives the professional graphic files from the project owner, the freelancer will replace the graphipcs of the game, including some animation of the fruits or the chess pieces. The freelancer will also find some sound file to add to the game until the project owner supplies him with custom music and effects. So the final prototype should be ready to show customer as a free minigame they can play and enjoy. Game should work on Chrome browser also. Some documentation inside the code should be provided.
