-- Each player has two bulldozers to move the rocks.
-- A bulldozer moving without pushing anything has a base speed V.
-- When a bulldozer pushes a small rock, the combined speed is V/2.
-- When a bulldozer pushes a medium rock, the combined speed is V/4.
-- When a bulldozer pushes a large rock, the combined speed is V/8.
-- When two bulldozers push a rock together, one behind the other, the pushing speeds are doubled compared to the speed of a single bulldozer.
-- The human player clicks on a rock to command the nearest free bulldozer to push it towards the ComputerZone.
-- The computer-controlled bulldozers randomly choose a rock and push it towards the HumanZone.
-- If a human bulldozer is free, the player can click on a rock already being pushed to have the bulldozer move behind the first one and push the rock faster.
-- It is possible to push a rock that is being pushed by the opponent to block or slow down its movement. If a second bulldozer is added in this situation, the rock will be pushed in the direction where there are fewer bulldozers.
-- The game ends when all rocks have been moved out of the RoadZone. The winner is the one with the highest score, based on the number and size of rocks successfully moved to the opposing zone.
-- The goal for the human player is to move all the rocks to the ComputerZone while preventing the computer from doing the same. Effective strategy and skillful bulldozer management are necessary to maximize the score.
-There is no time limit in this game, and players must use their judgment to determine the best way to move rocks and use their bulldozers to win the game.
