Tutorial

• Reworked the first-day tutorial into an optional task tracker with shorter, action-focused objectives.
• Tutorial progress and the tracker's collapsed state are now saved correctly, while improved screen handling keeps the tracker from obstructing or blocking other interfaces.
• Improved the scripted first customer and fixed tutorial crashes, duplicate quest cards, fish-lock tracking, and negotiation softlocks.

Skill Tree and Progression

• Added a complete Skill Tree with 20 skills across Customer Relations, Fish Care, Breeding, and Business.
• Added Shop Levels, XP, Skill Points, prerequisites, and persistent gameplay effects for purchased skills.
• Added progression milestones, end-of-day XP breakdowns, catch-up rewards for existing saves, and a notification badge for unspent Skill Points.

Tanks and Fish

• Reworked fish movement with more natural routes, smoother turning, better wall avoidance, loose schooling, and improved separation.
• Improved aggression chases, escape behavior, collision handling, and the movement of large fish in smaller tanks.
• Fish can now be dragged to a new position inside their tank, with their new position saved automatically.
• Improved preview movement and added depth tinting so fish sit more naturally within aquariums.
• Improved sponge-cleaning performance. Cleaning no longer stutters or lags on larger tanks and bigger sponge upgrades, and now runs on the graphics card instead of the processor.
• Added assisted cleaning completion after reaching 85% cleanliness, made lighting react to cleanliness, and fixed distorted dirt previews.
• Added more tank feedback, including fish-placement splashes, click ripples, feeding reactions, cleaning sparkles, and smoother progress bars.
• Reworked fish growth. Baby fish now start small and grow steadily to full size as they age.
• The Auto Feeder no longer reacts while the tank is locked or being cleaned, and now squishes when activated or deactivated.
• Fixed egg hatch tooltips being cut off near the edge of the screen.

New Fish

• Added six new Guppy varieties: Blue, White, Leo, Koi, and Flame.
• Male and female Guppies now have distinct appearances.
• Guppy swimming animations are tuned per variety and gender, giving each combination its own movement.

Fish Animation

• Swimming animations now match each species' actual speed.

Shop and Customers

• Fixed customers changing their requested species or quantity during an interaction and fixed two-fish requests being rejected incorrectly.
• Customer conversations now flow directly into the fish selection screen instead of displaying the customer's request twice.
• Customer counter-offer prices now update instantly in the price field before the customer's chat message types out.
• When you tell a customer "Can't help you today," they are permanently removed from that day's customer queue and will no longer unexpectedly return.
• Corrected lifespan quiz answers and improved tank-condition questions.
• Improved singular and plural dialogue phrasing and removed a redundant negotiation step.
• Rebalanced World Events so negative events are less common, cannot occur consecutively, and have limited strength and duration.
• Prevented negative market conditions from leaving a stocked shop without enough customers when suitable fish and visitors are available.

Internet and Trade Hub

• Added the Guides section with information about fish care, shopping, trading, licenses, breeding, customers, and shop management.
• Expanded Trade Hub stock so Uncommon and Legendary fish can now appear alongside the other intended rarities.
• Added first-time explanations for Internet sections and World Events; notifications now pause while hovered.
• Added Fish Store filter result counts and restored previous page positions when returning to Internet sections.

Interface, Feedback, and Audio

• Standardized the top navigation, improved store-name fitting, and added a compact five-star Shop rating display.
• Added visual reactions when important values change and fixed outdated money values briefly appearing when entering a tank.
• Fixed repeated sale-income feedback and added visible autosave confirmations.
• Improved Fish List wrapping and clipping so long names and status icons no longer overlap.
• Added sound feedback to previously silent buttons. Roughly 39 buttons across the game now have proper click feedback, including:
  • Shop screen: "Let's See", "Just a Second", "Send Away", quiz answer buttons, the shop builder button, and the tank overview close button.
  • Fish selection: add fish, price up/down, and "Nevermind".
  • Tank screen: fish detail panel tabs, the fish list toggle, rename, pickup, and the next/previous fish arrows.
  • Pause menu: Back to Game, Save, Load Game, Quit, and all save/delete confirmation buttons.
  • Main menu: save deletion confirm and cancel.
  • Tanks overview: settings and tank size selection.
  • Day summary: Return to Day, End Day Anyway, and Next Day.
  • Inventory: back, decoration edit toggle, quick sell, and rename.

• Fixed audio volume sliders not updating correctly. SFX and OST volumes now independently adjust the proper audio buses.
  
• Reduced slider sound spam, added subtle pitch variation, and improved interface animations.
  

Fixes and Stability

• Fixed crashes involving fish sales, Trade Hub purchases, fish eggs, tutorial saving, and Tank Shop asset cards.
• Fixed an end-of-day error when removing dead fish from tank data.
• Fixed the "buy a second tank" quest not recognizing players who already owned multiple tanks.
• Fixed runtime errors caused by interrupted animations or missing animation metadata.
