Alpha 12 - Patch Notes

* 2x3 and 3x2 grid sized ship canvases added to the game. You can start building on these bigger canvases by clicking the build new ship and switching out the default canvas.
* Logistics robots and a logistics robot station implemented.
* Salvage robots and a salvage robot station implemented.
* You can now build windows! These can be placed both on the ship hull and on walls inside your ship.
* Windows come in different variations, from 2 tile wide to 4 tile wide.
* Windows work as a source of light.
* Modified NPC ships, stations and derelict ships to have windows.
* Roofs are now visible by default on ships, which have not yet been visited or explored by the player.
* Created a hull paint generator, which creates color patterns on spaceships and station hulls.
* Created various tools for the hull painter to create your own color patterns on your ships.
* Added tile decorations to the roofs of ships and stations.
* Modified the sound space to not be as quiet as before. Note that the sound volume of elements is dynamic, it is based on the current zoom level.
* Added more sounds to the game: Industry facilities, power generators, power nodes and thermal regulators, Hyperdrives.
* Added some sounds for characters too, when they walk (zoom in to hear it), when they take a hit from an enemy, idle whistle and more. Some sounds are only played when
zoomed in close enough, to not overwhelm the sound space with too many sounds all at once.
* User interface sounds and game sounds now have their own separate volume setting in the game options.
* Added a resource prioritization option to airlocks. You can use this to specify to which airlock certain resources should be transported.
* Added some history graphs to the various view modes, tracking values over a period of time and shows them in a graph.
* The vents view mode has two new buttons. One for opening all vents on a ship, and one for closing all of them.
* Implemented a statistics menu, with various graphs containing historical data on how one or more resources have been produced and consumed over a span of time.
* Added also miscellaneous data, like the average mood of crew members over time, or the amount of prisoners over time.
* Thrusters for shuttles, mining pods and crew members have been modified and improved visually, to better fit their respective graphics and to reflect the
movement correctly.
* Improved and added more features to the user interface when using drafted shuttles to dock to ships/stations.
* Modified the link type UI section in the power view mode. Added an expert mode button to reveal the advanced link types. Added a new special type of link,
which allows you to create a link, which only moves power when capacity is over a threshold.
* Added a tooltip showing what type of resources are in crates visible on the floor. This will make it easier to see what's actually in the crate piles on derelict ships for example.
* Created a new wide styled ship for: Android Collective, Civilians.
* Modified and improved in-game icons.
* Improved various graphics.
* Balancing: Increased the CO2 need for plants and decreased the CO2 generation of crew members, with the aim to make the CO2 producer actually needed for optimal plant growth.
* Balancing: Chemicals costs more raw chemicals to produce.
* Added prison areas for all Military NPC ships.
* Added nuts and seeds as an option in the composter facility.
* Fixed bugs.
