Create a 2D Flappy Bird-style game called "Flappy Onion". The main character is a round orange onion with big white eyes and a green stem (I will upload my own image as the sprite). Instead of green pipes, the obstacles are silver kitchen knives hanging vertically. When you tap or click, the onion jumps. Otherwise, it falls. Add a score counter that increases when the onion passes a knife. Game ends when it touches a knife or the ground. Background: light kitchen theme. Sound FX: flap and crash. Allow me to replace the default sprite with my uploaded onion image.
