knagaitsev/slither.io-clone ? reverse-engineered prompt

Build me a playable Slither.io style game in JavaScript with Phaser, focused on the core single player experience, not multiplayer.

I want a snake that follows the mouse and also works with the arrow keys, with spacebar speed boost, food scattered around the map, growth when the snake eats, and death when the head hits another snake or itself. Please include bot snakes too, so it feels like a real game, plus the little details that make it fun, like eyes, shadows, and food dropped when a snake dies.

Keep it simple and polished, so I can run it in the browser and play right away. If you need to look up current Phaser docs online, go ahead and do that. Make it feel close to the classic Slither.io vibe, but without any server side multiplayer stuff.
