Gameplay & Simulation

• Added proper inspection for traders and thermal vents via right-click.

• Health display improved; hidden for volcanoes and traders where irrelevant.

• Prevented selling the main shipyard to avoid soft-locking the session.

• Underwater habitat beacon updated.

• Fixed excessive resource stacks in trade convoys caused by legacy import logic.

• Improved oxygen simulation:

  • Added citywide oxygen bar.

  • Habitat tiers clarified: Tier 1 always consumes oxygen but not food.

  • Tier 2 and higher now use food resources; starvation audio restricted accordingly.

• Added oxygen and food deprivation sound effects (gasping, hunger growls).

• Fire simulation updated:

  • Fires consume oxygen in the building inventory.

  • When oxygen reaches zero, all occupants die and the fire extinguishes.

  • Random death events return for habitat fires.

• Collapse, fire, and risk rates increased; deep-sea high-pressure regions further amplify collapse danger.

• Deep-sea biomes now apply ambient damage (up to 1 damage, 10 times per minute).

• Wheat and aquaberry farms no longer function in deep-sea biomes; these must be imported.

• Food requirements no longer scale with habitat leveling to maintain manageable progression.

• Markets, schools, and theaters now operate based on distance:

  • Market: 1 tile

  • School: 2 tiles

  • Theater: 3 tiles

• Added operational radius indicators and updated tooltips.

• Markets can now handle aquaberries for feeding nearby habitats.

UI & Interaction

• ESC improvements:

  • ESC closes the inspector.

  • ESC can also close the ESC menu itself.

  • Right-click can exit the trade menu and ESC menu.

  • Added darkened background layer under the ESC menu.

• Cursor fixes:

  • Cursor no longer disappears when interacting with the minimap.

  • Cursor re-enables properly after minimap clicks.

  • Cursor hiding logic corrected.

• Resources always visible unless specifically restricted for trading.

• Added descend beacon visual and a to-do list for upcoming icons.

• Tier 1 habitat descriptions updated.

• Citywide oxygen bar added for clearer feedback.

• Updated underwater UI visuals and warehouse menus.

• Import/export warehouse visuals reworked; building layout aligned.

• Population and city rating displays now visible by default.

• Build date now shown on-screen.

• Grass now hides automatically beneath structures.

• Clicking a new build button now cancels previous placement.

• Build menu behavior improved to prevent accidental multi-placement.

• Building button hider fixed—buttons now import correctly before being hidden.

• Added pulsing highlight effect to certain UI buttons.

Art & Visuals

• Building glass recolored to a blue-grey tone.

• Updated farm graphics and seabed fidelity.

• Added visuals for aquaberries.

• Deep-sea lighting tests implemented.

• Deep-sea lights now disabled in non-deep-sea missions.

• Added whale skeleton generator for deep-sea environments.

• Implemented full deep-sea magma biome.

World, Biomes & Environment

• New shortcuts in the main menu for quickly loading specific biome test scenarios:

  • Enemy encounters

  • Deep-sea darkness

  • Magma

  • Magma + darkness

• Traders now correctly rotate before moving.

• Mutants and pirates no longer spawn in editor test mode.

• Enemy spawn settings and timing now work consistently across all missions.

• Light combat features added.

• Metal and oil nodes now provide tooltips.

• Updated obstacle removal system—now safer and cannot desync between visual and data states.

Audio

• Suffocation, gasping, and starvation audio added.

• Increased gasping volume for low-oxygen warnings.

• Habitat starvation audio suppressed before Tier 2 requirements.

Missions & Objectives

• Mission 1 objectives updated and rewritten for clarity.

• All objectives for Missions 1 and 2 fully implemented.

• Mission 3 objectives system set up.

• Objective scripts cleaned and reorganized.

• Objective building-placement checker rewritten for higher reliability.

• Enemy wave spawn timer updated.

Progression, Rewards & Meta Systems

• Total upgrade bonuses now displayed in the main menu.

• Added a basic card-style upgrade system to the main menu.

• Rewards can now be clicked to select upgrades.

• Balance revised:

  • Losses provide significantly lower rewards.

  • Wins provide higher rewards.

• Fixed bug where the game always remembered the last mission as a win.

• Improved end-of-mission and victory screen transitions.

• Work begun on post-game summary screen featuring reactions based on player performance.

Technical & Stability

• Fixed cases where oxygen transfer errors occurred between import centers and warehouses.

• Fixed null checks related to goods unloading.

• Disabled demo resources; replaced with full resource set.

• Added extensive safety logic to prevent resource-retrieval subs from launching before origin structures are fully initialized.

• Increased collider sizes on buildings to improve clicking accuracy.

• Fixed issues where node-based buildings could be placed more times than available nodes.

• Fixed unemployment bug.

• Updated various tooltips, including medic facilities and trade relations.
