Now I'll build a fun dog game -- a "Bone Catcher" where you move a dog left and right to catch falling bones while avoiding obstacles. Let me create the themed globals, update the layout, and build the game components.
Now let me create the game components:
Here's your dog game -- Bone Catcher! You play as a cute pup on a grassy field under a blue sky. Bones, treats, and balls fall from the sky and you move the dog left/right to catch them for points. Avoid the bombs or you lose a life, and missing a good item also costs you a life. The game tracks your score and high score, with difficulty increasing as your score climbs.
Controls: touch/swipe on mobile, mouse movement on desktop, or arrow keys / A and D. The game is fully canvas-rendered with particle effects for catches and hits, animated clouds, and swaying grass blades.
