ESTELA: Space Comet Arcade

One touch. One comet. A trail of light that kills you. Fly from the Sun to interstellar space and discover the cosmos as you go.

Your only rival is yourself.

You pilot a comet that paints a permanent trail of light. There are no obstacles designed by anyone: the only thing that can kill you is the trail you just painted yourself. The better you dodge, the more beautiful and more lethal the level becomes, because you are the one building it.

ONE FINGER Hold to curve one way. Release to curve the other. That's the whole game. Three seconds to learn, never to master.

YOUR TRAIL KILLS YOU The freshest part is safe, but as it ages it turns deadly. Nobody can memorise the level, because the level is you.

SOLAR WIND Collect sparks of stardust. Every seven unleash the solar wind, which burns away your old trail and gives you back the arena. Every ten trigger overdrive and your metres count double.

A REAL JOURNEY THROUGH SPACE The further you fly, the further you travel across the cosmos: from the Sun's corona to Mercury, Mars, the asteroid belt, Jupiter, ringed Saturn and, if you last, interstellar space. Thirteen real regions, each with its own atmosphere, its own world and a scientific fact recorded in your Logbook.

SIX REAL COMETS Unlock Halley, Encke, NEOWISE, Lovejoy, Hale-Bopp and Oumuamua, the first interstellar visitor ever detected. Each with its own story.

And when you die, the screen is left holding a painting of light that only you have ever made. Share it and dare anyone to beat it.

No internet. No sign-up. No accounts.
