An arcade-style puzzlement of acumen and determination!
Face off against sea creatures of three shapes and sizes! Dive for treasures, but don't get too cocky! Try to resurface in one piece!  Mark your existence upon the LEADERBOARD! Do it all forever ENDLESSLY and beat your high-score, over and over again! . . but only after you make it safely back to harbour in the CAMPAIGN! A soul successor to the critically-unacclaimed Kaitei Takara Sagashi (海底宝探し), an arcade marvel of the year 1980.

Do you have what it takes to be the UNDERWATERTREASUREHUNTER?
