Fans of Sega's Sonic the Hedgehog games know all too well what happens when Sonic is underwater for too long. The happy, upbeat music of the zone quickly gives way to a pulse-pounding, heart-stopping tune of danger. The beats quicken, the tempo picks up, and if poor Sonic can't find air before it's over (a mere five-count), there's a momentary beat of silence and then... GLUGGGGGG our hero drowns. There's a whole generation of gamers out there who feel their anxiety involuntarily spike when they hear that warning song.
A few days ago I was playing the new Sonic Mania and revisiting the joys of Chemical Plant Zone when I faltered and had to race to the top of the flooded chamber before Sonic's air ran out. The video below is what happened. My heart is still racing.
