Starfling: A one-tap endless orbital slingshot game in a single HTML file

Gameplay

Starfling is a tiny, immediate game about timing and geometry: tap to fling a little ship around planets, use gravity to chain slingshots, and try not to fall into a star. It’s one-button simplicity—easy to learn, hard to master. The thrill is in the snap decisions: hold too long and you overshoot, tap too soon and you bonk. Tiny joys, big tension. Who doesn’t love a quick game that respects your time?

Single-file craft

It has been reported that the entire experience is contained in a single HTML file served from playstarfling.com — a neat bit of engineering that feels like a demo-scene trick for the browser age. Under the hood you can see the usual suspects — JavaScript and canvas-ish rendering — stretched to do a lot with very little. There’s a particular pleasure in constraint: when a game fits in one file, you can open it, poke the source, and learn something in minutes.

Reception and why it matters

The title has popped up on Hacker News and similar corners of the internet, where readers praise its economy of design and addictive pocket-sized gameplay. It’s a reminder that good ideas don’t need huge studios or giant budgets; sometimes a single HTML file and a neat mechanic are enough to grab attention. Want to try?
