Make a simple game where a duck wants to cross a road filled with moving cars. The player can draw lines or shapes with their finger/mouse to help the duck cross safely. Lines act as temporary crosswalks or barriers that guide or block. Shapes fade after a few seconds. The duck moves only when the player stops drawing. Goal: get the duck across all lanes without being hit by traffic.

Instead of just boxes traffic includes cars, buses, bicycles, and even random animals like coes or turtles
