Unlock Fun with Our Word Guess Puzzle Game!

Design a vibrant splash screen for a Word Guess Puzzle game with a brain-inspired background. The background should feature a detailed 2D brain illustration, with neural pathways and glowing synapses in soft pastel colors (light pinks, blues, and yellows) to evoke a playful and lighthearted atmosphere. In the center, create a typographical logo for 'YiYi' in a chunky, rounded, and slightly glossy candy-like aesthetic. The letters should have a vibrant mix of pastel pink, sky blue, and lemon yellow, resembling candy pieces. Surrounding the logo, floating alphabet tiles, shaped like colorful jelly or gummy pieces, hover and bounce playfully in various sizes and orientations, with soft transparency and a squishy texture. The background should have a soft swirl or abstract pattern in pastel hues, enhancing the energetic and fun vibe of the game. The floating letters should feel dynamic, as though they are actively part of an engaging word game.
