Create drag-and-drop brick construction game for 3-year-olds

[Copilot]

Implements a Windows PC game for early childhood education focusing on motor skills and spatial awareness through brick construction. No text, no scores, no failure states—pure constructive play.

Implementation

• Core mechanics: Mouse-only drag-and-drop with 30px grid snapping and 40px brick-to-brick snapping for motor skill development
• Visual design: 12 brick types (5 sizes × 7+ colors), LEGO-style studs, gradient fills, sparkle feedback on placement
• Tech stack: Vanilla HTML5/CSS3/JS game engine wrapped in Electron v35.7.5 for Windows deployment
• Safety: Offline-only, zero external dependencies, no data collection

Original prompt

You are an expert early-childhood game designer. Create a Windows PC game for a 3-year-old focused on brick construction using drag and drop. Use large, colorful blocks that snap together gently. No text, no scores, no failure states. Mouse-based drag & drop only. Calm sounds, slow animations, positive visual feedback. Simple builds like towers or houses. Safe, offline-friendly, and designed to improve motor skills and spatial awareness.
