About this game

Drag across adjacent tiles on a letter grid to spell valid words and rack up score before your oxygen meter empties. Each word found refills your air and chains into multipliers, while rising score sinks you to deeper, harder library depths that introduce locked, glowing, and cracking tiles plus upgrade choices. A tense word hunt wrapped in a moody amber-and-deep-sea diving theme.
