How to play Astro Explorer

  1. Run with A / D or the arrow keys and jump with Space or W. Hold jump to go higher.
  2. Swing the energy blade with J or X; hold ↑ to strike upwards. In mid-air, hold ↓ and swing to bounce off aliens and spikes.
  3. Blade hits charge the blaster (K or C). Stand still and hold ↓ to turn 3 energy into an armour plate.
  4. Each planet hides an ability capsule: double jump, then dash (L, Shift or V), then wall-cling. New moves open up secrets.
  5. Light the rest beacon to repair your suit and spend star dust on armour, blade and blaster upgrades. Every fifth planet is a guardian’s lair, then a treasure vault.
  6. On a phone, use the stick to run and aim, plus the JUMP, BLADE, BLAST and DASH buttons.

Controls: A / D or ← → run · Space / W jump · J or X blade · K or C blaster · L, Shift or V dash · ↑ ↓ aim · hold ↓ to heal · on touch: stick + JUMP, BLADE, BLAST, DASH.

💡 Cracked rock can be broken with the blade, and there’s always something behind it.
