Amazing game. I'm assuming this is still in development considering some of the textures seem polished(love those ones by the way, very easy to tell apart while zoomed out but also hold up zoomed in) while the gemstone pickaxe also exists, but despite that I haven't encountered any game-breaking bugs. I haven't even had it for 24 hours yet, so it may just be that I haven't played long enough. All I've found for bugs is that op cursor doesn't work on browser for me(very sad), and if you zoom in on the green part of a ship's flight path you can see that the green segment is in reality shaking violently. I've only seen the second one once, though, in galaxy view, and if the second one is your next priority to fix you're either incredible at coding or horrible at bug finding.
also sorry for the long comment, especially if it came off as negative anywhere. I am in love with this game so far.
