A CLASSIC RADIAL TUNNEL SHOOTER
Machines climb out of the observatory. Rotate around the rim and fire down their spokes. Every machine that reaches the rim breaks a shield. Clear each depth to descend.
ROTATE & FIRE
← → or A / D rotate; hold Space to fire. Touch: use the joystick or direction buttons and hold FIRE. The ivory spoke shows where your shots go.
READ THE MACHINES
Diamonds climb straight. Bow ties switch spokes after flashing. Needles grow long spines. Plated hexagons need two hits. Winged machines surge after a warning.
MAKE A RECOVERY
X / PULSE destroys machines beyond the inner quarter of the tunnel. Two charges per depth through 5. A broken shield clears the outer rim and gives 2 seconds of protection through depth 6. Depth 7 has brief protection and no rim clearance: aim for no breaches.
P pauses · R resets · M toggles sound. Shields and pulse charges refill each depth. Retry keeps your score from the start of that depth.
