I just released the game's early access version, its now available for purchase!. Remember the only difference with the demo is that the full version has save game functionality, it automatically saves the game when you exit a base, or the planet map.
Let me know what you think, in the next coming days I'll be listening to player's feedback, mostly fixing bugs, but also trying to add the most requested features.
I hope you have lots of fun with "Planetary exploration company"! :D
