ASTRA has eleven achievements. Each one you unlock grants a title, and you can display any title you own

2. The ones that unlock themselves
First Light, Star Collector, Little Galaxy and A Hundred Voyages depend only
on
how much you play. Every run makes a star, including bad ones, so even three-tap runs move them along.
Keep playing and you will pass all four without trying.
A Thousand Sparks counts successful taps. If you average 20 hits a run, that is about 50 runs.
3. The ones that need a score
Chasing Meteors (best 100) and Mythic Realm (best 320) require reaching those
numbers in a single run. Difficulty and streak multipliers both apply, so stacking them lowers the combo you
need.
Target
Normal, 1-day streak
Hard, 10-day streak
Score 100
~14 consecutive hits
~10 consecutive hits
Score 320
~25 consecutive hits
~18 consecutive hits
Tip: the run that takes your best to 320 necessarily produces a MYTHIC star, which means
Mythic Realm and Mythic Discovery unlock together.
The shortest path is to build a 10-day streak for the 1.5× multiplier first, then go for it.
4. The one that needs all three difficulties
Three Orbits requires a best of 50 or more on Easy, Normal and Hard.
If you always play the same difficulty, this tends to be the last one standing. Fifty is not a demanding number
—
a handful of runs on each of the other two settings clears it.
5. The one that needs time
Seven Nights requires playing seven days in a row. Missing a day resets the count to 1,
so this one cannot be rushed. Days are counted in Japan Standard Time.
Your streak also drives the score multiplier, reaching 1.5× at ten days.
By the time Seven Nights unlocks you are already at 1.35×, which makes it a good moment to chase the score
achievements while the multiplier is high.
6. The one that needs PERFECTs
Perfect Resonance unlocks when the PERFECTs recorded across all the stars in your galaxy total
50.
It is cumulative across every run you have ever played, not a single-run target.
A PERFECT is a tap within the central 30% of the gate. The window is tight but the points double,
so this tends to accumulate on its own while you chase scores.
7. Using titles
Titles you have unlocked can be swapped at any time from "Choose title" on the home screen.
Earning a new one never removes an old one, and titles have no effect on difficulty or scoring.
