Your **Numberblocks Playground** is ready! Here's what's in it:

**Gameplay:**
- **Drag blocks together** to add them (e.g., drag 2 onto 3 to make 5!)
- **Tap a block** to split it in half (e.g., tap 6 to get 3 + 3)
- **Tap the colorful number bar** at the bottom to spawn new blocks (1-10)
- **Challenges** appear asking you to make a target number for bonus points

**Features:**
- 10 unique Numberblocks characters (1-10) with authentic stacked-block layouts
- Googly blinking eyes, smiling faces, and bouncy physics
- Sparkle particle effects when blocks combine
- Combo system for chaining merges
- Score tracking with leaderboard submission
- Synthesized sound effects (pickup, combine, split, celebrate)
- Beautiful cartoon background with animated grass
- Keyboard shortcuts: 1-9 to spawn, C for new challenge

**Next Ideas:**
1. **Multiplication Mode** - Add a mode where dragging blocks side-by-side multiplies them (2 x 3 = 6), teaching times tables alongside addition
2. **Numberblock Animations** - Add walking, jumping, and dancing animations so blocks come alive when they're happy or celebrating a challenge
