Nice game, I just finished it (on easy difficulty only though).

Are you planning to have some victory screen with various scores etc?
Currently there's just "You saved the galaxy!" label in the top corner
and the game seems to go on.

Also allowing to change the size of the window would be nice (not just small window/fullscreen options).

And maybe more levels of Logistics research? I've built fixer ships in visited sectors to repair
defense drones when my mothership was away, but later I've hit max ships limit and have to finish the game
with just 2 ships in the mothership's formation.
