I like the idea and I love the ambition. I usually love 4x games, so this is in my wheelhouse, but I didn't get very far.
I'll be honest and straightforward because that the kind of feedback I'm hoping to receive. Platitudes are nice, but critical feedback is more helpful. Please don't think I hated the game or anything like that.
First impression: The tutorial is nice. Simple, unobtrusive, effective. Game concept is great. Galaxy map is great. moving and zooming feels good. Some ambient audio or background music might be nice.
Second impression: I wished my colony could build a telescope, since all my early attempts at exploring resulted in bad outcomes with inappropriate stars, which ended up costing me money.
Is there a way to dismantle a colony that's costing money?
Oops, I didn't realize the menu would end my game.
Third impression. Learning the optimal build-sequence to get through the important first few steps of a new 4x game is sometimes tedious, A let's play walkthrough or a small strategy guide would come in handy.
I feel like I'm trying to make decisions without any information. How many fighters would it take to conquer a planet? Which planet should I send my next colony ship toward? It seems like guessing.
(It's possible that I missed something obvious, or that I'm bad at strategy games)
