This is a very good game, it has many features. However, there is no clear directions about anything. You (more or less as there is an encyclopedia) have to explore everything yourself. Maybe add a tutorial at the beginning of the game? Show how basically everything works… it’s a very confusing game at the moment.
Developer Response
Thanks for your wonderful rating and great feedback. A tutorial added into version 1.3.3 to introduce the basic UI elements.

Game Crash Issues Game is good, but found that the game frequently crashes whenever you’re far ahead of the other CPU players within the game. Can this bug be fixed? Game Play Instructions Unclear Like the New Galaxy Mode. What’s unclear is how to take over other planets. Do you just send as many ships possible for the best, or is there a particular way as intended? Glitches and Bugs after winning Game I found with after “winning” the game, the game doesn’t allow you to change the percentage tax rates, or unable to switch government types after it falls into anarchy (under Democracy due to unhappiness) - being stuck in “Revolution” mode. I used the anarchy glitch to my advantage with the British Isles mode in a save file (before that game mode was removed in later versions), but unable to go back to one of the government types or set the tax rates. Can this bug be fixed?Edit: [04-22-2023] I found the Game File doesn’t save when you get Victory over all the other Players. As a result, it always goes back to the turn before you win the game. Can you create the option to continue playing in the same Game File after Victory?

Thanks for your good rating and feedback.To take over another planet, would you like try to transport your colonist to the target planet? They will fight for you.
Great game

I’ve been playing for a few months and while I admit I’m not fantastic at the game I will say it always keeps me coming back. Love the updates and new maps! Excellent work!
