New update has quite a few changes to production. The refinery by default now only outputs metal and water. It must be upgraded before it can also produce fuel and air (research unlock, followed by upgrade). To give you another option here though, I have also added the electrolyser item. This takes water and outputs fuel and air. You'll now have to weigh up having a refinery and electrolyser, and/or researching the advanced refinery. Electrolyser is more efficient than the advanced refinery, but outputs fuel/air at a set rate, the advanced refinery fuel/air/water output ratio can be configured. The advanced refinery also takes less power than the basic refinery and electrolyser combined. I've also made balancing changes whilst looking at production/efficiencies. The low/no O2 penalty has now been reduced. Less ore usage by the refinery. and fuel/air output adjustments. Probably will be further tweaks here, so any feedback welcome. Couple fixes as well, main one being shields weren't always detecting pirate lasers. Since i expanded shield range, it was now possible for a pirate, laser and it's target to all be within the shield circle. Wasn't checking for this simple case, doh! Patch notes:-

• New electrolyser item.
• New research item - Advanced Refinery
• Refinery only outputs metal and water.
• New upgrade option on refinery. Once upgraded, fuel/air/water ratios can be configured.
• Improve: Low/no O2 production penalty reduced.
• Improve: Reduce refinery ore input figure.
• Fix: Shield check on pirate laser, need to also check if laser doesn't cross shield circumference.
• Fix: Game over check add no metal / no metal storage unrecoverable state.
• Fix: Issue loading save files, when in-game. O2 balancing not using updated floor tile count.
