Update 01.133: This week we are adding collision/impact sounds for all metal objects - tools, components and ships. The final sound is dependent on the mass of the objects. Heavier items produce louder and more bassy sounds.
Also, music is now divided into different categories (space, planet, building, fighting etc) and played according to the current game situation e.g. building theme when building, fighting theme when fighting. Connectors should be much more stable after today's update as we have introduced something that we call "connector welding". They now function similar to landing gears where two ships connecting together will become one physical object. Finally, weapon spread has been added to the game.
