Thanks for all the feedback you have provided!
The free Alpha is over. InfraSpace has grown a lot and it's time we release it to the greater community to fund further development (we've been releasing weekly free updates without earning a penny for 7 months now).
InfraSpace will be released into Early Access on October 15th and you can get it on Steam, GoG, or Humble.
We hope you enjoy playing the game as much as we enjoyed making it. Happy playing!
