Done! I've changed the background from the purple-to-blue gradient to a solid pink. The memory game now has a vibrant pink background while keeping all the interactive card elements and gameplay mechanics intact.

Done! I've replaced the reset button with a big, eye-catching refresh button at the bottom. The button now has larger padding (py-8), bigger text (text-2xl), a refresh emoji icon, and interactive hover effects that scale up on hover and down on click, making it perfect for mobile touch interactions.
