I remember playing that. My strategy was to breast-stroke as fast as I could while not quite scraping the bottom of the pool with my chest. I usually came out pretty well in the end :) We would also do exercises in the diving pool of treading water for a half hour+ at a time. Good times. (I was also around 12)
