Power-ups
Destroying a rock sometimes drops a power-up. Fly into it to pick it up — bigger rocks drop power-ups more often than smaller ones. There are four kinds:
- Shield — absorbs the next hit you take, then disappears; if nothing hits you first, it wears off on its own after 8 seconds.
- Rapid-fire — cuts the cooldown between shots from the default 0.22 seconds down to 0.08 seconds for 8 seconds, so you fire noticeably faster.
- Score multiplier — doubles the points you earn from every rock you destroy for 8 seconds.
- Slow-time field — slows every rock and your own drifting momentum to 45% speed for 5 seconds, giving you more room to dodge and aim.
The Slingshot Bonus
Gravity is always pulling your ship toward the planet at the center of the screen. Fly a close, fast pass near it — within about 140 pixels at a speed of at least 120 — and you trigger a slingshot: the game flashes "SLINGSHOT! x2 for 4s" and doubles your score for the next 4 seconds, the same doubling a score-multiplier power-up gives. You can't trigger another slingshot for at least 1.2 seconds after the last one, so line up your next close pass rather than hugging the planet constantly.
Scoring
Destroying a rock scores points based on its size: large rocks are worth 20 points, medium rocks 50, and the smallest rocks 120 — the smallest are worth the most individually because a large rock splits into two medium rocks when destroyed, and each medium rock splits again into two of the smallest, so a single large rock's whole family is worth hundreds of points once every fragment is cleared. Chaining kills builds a combo: every consecutive kill within 2.5 seconds of the last adds +0.5x to your score multiplier, capped at 5x, and a slingshot or score-multiplier power-up doubles whatever that combo already earns.
5 Tips for a Higher Score
- Finish off every fragment a large rock splits into — the smallest fragments are worth the most points each, so a fully cleared lineage is worth far more than the rock you started with.
- Keep your kills within 2.5 seconds of each other to build your combo streak; each consecutive kill adds +0.5x to your score multiplier, up to a 5x cap.
- Time a slingshot pass near the planet right before a big combo — the double-score window lasts 4 seconds, so stack it on top of your highest-multiplier kills.
- Grab every power-up a destroyed rock drops: a shield banks a free hit, rapid-fire and the score multiplier both pair well with combo chains, and a slow-time field is the safest way to survive a crowded wave.
- Manage your orbit instead of fighting gravity — thrust to adjust your path around the planet rather than straight at or away from it, and on boss waves (every 5th wave) clear the regular rocks first to build a combo before you engage the boss.
