Wow, those were some busy months at BugByte but I really admire the effect - so many great additions to Space Haven.
I especially like the power grid/nodes system as it allows for further development.
For example you could mine 'normal' ore/minerals that give, let's say +100 power but you could risk searching for 'enriched' ore/minerals that power you up for +250.
Negative effects could be 'solar flares' events that reduce your power production by -50% and you have to think how to compensate for that.
Regarding early access - any chance for GOG alpha version for non-Steam users like me?
