Remix: Toddler Herding

Build a small, playable browser game inspired by "Toddler Herding" (Puzzle, Strategy, Simulation).
Concept: Embrace the (chaotic) experience of walking a toddler through the neighborhood to the nearby playground while managing their curiosity, lack of spatial awareness, and finicky attention span. You can try to get to the playground quickly, but you might sacrifice their happiness. But letting them whatever they want might risk never reaching the playground... Perhaps the answer will become apparent to you.
Tech: use Three.js; keep it to a single page that loads instantly with no login or install.
Controls: keyboard and mouse on desktop, shown on a short how-to-play screen.
Players: single-player.
Audio: add simple sound effects and music (start audio on the first click/tap).
Steps: 1) get the core mechanic playable with placeholder shapes, 2) add win/lose conditions and restart, 3) polish feel, visuals and sound, 4) add your own twist (setting, character or one new rule).
Make it your own: don't copy the original's name, art, text or code.
