Devourling

Devourling is an idle grower about a speck of gravity with an appetite. Matter drifts in and it eats. It eats while you play, it eats while you sleep, and it never, ever gets smaller.

ONE THUMB
• Tap to tug the nearest matter toward you. Drag to flick it in, with its arc drawn live.
• Anything you catch by hand counts five times over. Every so often a comet crosses: flick it in for a minute of eating in one bite.

ONE NUMBER
• Your mass is your size. Grow from speck to pebble to asteroid to moon to planet to star, then to black holes, galaxies, and the web that holds them all.
• Twenty phases, each with its own look, all the way to Everything.

IT EATS WHILE YOU'RE AWAY
• Close the app and the well keeps eating. Come back to an away report: what it ate, what it became, what it learned.
• Long Sleep stretches how long it keeps going without you.

DUST BUYS APPETITE
• Everything eaten leaves Dust. Spend it on twelve kinds of matter your well learns to eat, twenty-five levels each, every level a little faster forever.

RESEARCH TAKES TIME
• Put Dust into a project and let it run, in the app or out of it: a wider horizon, a finer sieve, colder storage, stickier fingers. What it finds is yours to keep.
• One research slot is free. Photons, earned with every phase or bought in the shop, open three more, finish a project early, or trade for Dust and skips.

Free all the way to the end: about four months of checking in a few times a day.

It has eyes. They follow your flicks. It blinks.
