+- At the start of the game, 10 rocks of three different sizes are randomly placed in the RoadZone.
+- 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.

+Game settings:
+- At the start of the game, 10 rocks of three different sizes (small, medium, large) are randomly placed in the RoadZone.
+- The rocks have square 100x100 pixels sprites centered (anchor 0.5, 0.5).
+- The Rocks have a front and a back zone to simulate a contact area with the Buldos.
+- Each rock is on its own horizontal 100 pixels wide line.
+- There are two players: the human player and the computer.
+- Each player has two Buldos to move the rocks, a kind of bulldozer.
+- The human Buldos are called "buldoRocks" and the computer Buldos are called "buldoZers".
+- The buldoRocks have a 100x100 pixels sprite centered (anchor 0.5, 0.5).
+- The buldoZers have a 100x100 pixels sprite centered (anchor 0.5, 0.5).
+- The Buldos have a front and a back zone to simulate the pushing of the rocks.
+- At the start of the game, the buldoRocks are placed in the HumanZone and the buldoZers are placed in the ComputerZone (abscissa centered and ordinate equally spaced 1/3, 2/3).
+- The buldoRocks are facing right and the buldoZers are facing left.
+Game rules:
+- The buldoZers are controlled by the computer and will move randomly (or futher with AI) to push the rocks towards the HumanZone.
+- The buldoRocks are controlled by the human player and will move when the player clicks or taps to push the rocks towards the ComputerZone.
+- The human player selects a buldoRock by clicking or tapping on it, then selects a rock to push by clicking or tapping on it.
+- The Buldos may only move in lignes, horizontally or vertically, and may not move diagonally.
+- When a Buldo is selected to push a rock, the Buldo must move to the ordonnate of the rock
+- To move to the ordonnate of the rock, the Buldo will probably have to make a 90 degres rotation, then move vertically up or down to the ordonnate of the rock, then make a 90 degres rotation to face the rock.
+- When a rock is entirely into the HumanZone or the ComputerZone, it is out of the game (loss of visibility of its sprite or destruction of the object Rock).
+- When a Buldo has finished pushing a rock, it comes back to its camp (HumanZone or ComputerZone) horizontally and once in its camp, it turns at 180 degres to face the RoadZone.
+- A Buldo moving without pushing anything has a base speed V (to futher adjust).
+- 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.
+- It is possible to push a rock that is being pushed by the opponent to block or slow down its movement.
+- If a second Buldo is added in this situation, the rock will be pushed in the direction where there are fewer Buldos.
+- 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 (small rock is 1 point, medium rock is 2 points, large rock is 3 points).
+- The goal for the human player is to move all the rocks to the ComputerZone while preventing the computer from doing the same.
+- 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 Buldos to win the game.
