You control one thing: the line. Hold (mouse, tap, or Space) to reel up. Release and the lure sinks on its own. Feather it to hold a depth.

Catching

• Fish live in depth bands. Sink your lure into a fish's band and it'll come investigate.
• When one bites, you're hooked. Reel to bring it up.
• Every fish fights. Reeling builds tension; when a fish dives, ease off or the line snaps and it's gone.
• Land it by bringing it to the surface.

Going deeper

• Sell catches for coins. Buy a longer line to descend — the rarest creatures glow in the dark far below.
• Stronger line resists tension, so you can land the monsters. A brighter lure draws fish in; a faster reel shortens the fight.
• Fill the journal. There are legends down there, and a few curiosities.
