Potentially Hazardous

Potentially Hazardous turns a near-earth object tracking network into a fast
visual search challenge. Numbered threat beacons scatter across a 5x5 radar
grid. Tap them in the required order as quickly as you can: a correct lock
extinguishes the beacon and builds your combo, while a wrong tap costs 2
seconds. Clear all 25 beacons before the countdown hits zero to secure the
sector.

Later sectors raise the stakes: a dense 6x6 grid with 36 beacons, reverse
order from 25 down to 1, and an odd-even alternation protocol that jumps
between the smallest odd and largest even target. The grid reshuffles every
round, so no two scans play the same.

Earn coins from fast clears and spend them in the Supply Depot on six field
tools: extra time, next-target ping, error shield, countdown freeze, combo
amplifier and a full radar sweep. Ratings from C to S reward sharp eyes and a
steady hand.
