The stack - landing a fish is now a game of Stacker. Stop each row of lamps on the one below; whatever hangs over falls away, and every row runs faster
The LANDED line - take your fish there with right mouse, or keep stacking with left mouse
The TROPHY line - three rows higher, for twice the value and a bigger fish. Slip above the LANDED line and the fish is gone
Perfect rows - a row stopped exactly on the one below adds 5% to the catch, up to 50%
Harder fish - rarer fish and the deeper baths need taller, faster stacks, and the rarest narrow the rows themselves
Back to the title screen - from the pause menu. In company it leaves the session first, and the baths pass to another angler
Quit - on the title screen and in the pause menu. It asks once before closing the game
Settings - picture, sound and controls on a page of their own, from the title screen or the pause menu
Glass doors - the sitting room opens for 10 memories from a Return, and stays open for good, through every later Return
New fish - all 37 species are new models, each based on a real animal: a common carp, a bream, a perch, an eel, a moray, a lungfish, a wels catfish, an oarfish, a mola, a John Dory, rays, soles, and an axolotl the attendant still insists is a fish
Photographic skins - every fish wears real scales or skin at its own scale size, under its own colours and markings, and looks wet, catching the light scale by scale
Swimming - fish bend as they swim, beat their fins and thrash on the line. The pools and the specimen tank hold the same fish you catch
The Screamfish - its jaw hangs open now
Line, rods and rhythm - steady the stack's rows instead of widening the old timing band. Reel tuning and some rods take rows off the stack
Company bonus - every other angler now steadies everyone's rows a little, instead of widening the timing band
Scoreboard - the best catch shows as a catch, with its grade and value, so a fish's name no longer reads like another angler's
Scoreboard spoilers - the scoreboard named another angler's catch before their reel had stopped
Doorways - the gaps beside the gates between the baths, where you could see into the next room, are closed
The timing band - pulling inside a moving band is gone. The stack replaces it
