Gravwell: arcade roguelite

The ship has no brakes. It drifts.

Gravwell is a take on Asteroids where gravity is the main mechanic: planets and black holes pull your ship AND the asteroids. You can see the well on screen and decide: dodge it, or ride the orbit and use the slingshot to cross the field without spending thrust.

CONTROL WITH WEIGHT
360-degree inertia: speeding up is easy, stopping is not. The stick sits fixed in the corner: direction aims the nose, distance thrusts. Let go and the ship keeps going. The screen edges are joined: leaving one side means entering the other, which serves to escape and to surprise.

EVERY RUN IS DIFFERENT
After each phase you pick one of three upgrades: fire rate, double shot, piercing, drone, shield, retro-brake, bomb. The combinations change how the ship behaves, and no run repeats the previous draw.

FOUR SECTORS, DIFFERENT GOALS
Clear the field, survive the clock, protect the core, or face the boss-asteroid that closes each sector. The Belt has a planet; Orbit has constant gravity; the Nebula has two planets at once; the Singularity has a black hole, with an event horizon that swallows ship and rock alike.

WHAT CARRIES OVER
Fragments earned by playing buy permanent upgrades in the Hangar: starting shield, an extra card in the draw, a head-start upgrade. They are earned, never sold.

NO ADS. NO PAY-TO-WIN.
There are no ads anywhere. Reviving is free, once per run. The store sells content (new sectors) and looks (theme, ship style). None of it helps your score. Everything that changes a run is earned by playing.

BUILT FOR PHONES
Neon vector art drawn in code. Left-handed layout, button size and sensitivity all adjustable. Six languages. Works offline.

A small game, made by one person, with no rush and no tricks.

Single player. Plays with no internet.

Recent changes:
Gravwell has its own look now: a new ship, cut-stone asteroids, a menu that shows the gravity well and longer music in every sector. Runs can be paused from the corner icon or the Back button. New: the slingshot (pass close to a planet at high speed to score points) and a predicted path while you are pulled. The Swift Ship has its own design, and your save is protected against power loss. Your progress stays as it was.
