Thank you so much for playing, it really feels amazing to hear from people spending so much time on the weird, rough game I put out there :)
The later galaxies still being quite slow is a really good point, I also had that feeling on my own playthroughs. The prestige upgrades definitely need some attention and I will think about to include skipping some of the slow and early parts more.
Also the settlement phase has been mentioned a few times now as a part that is not balanced well. I might space out the milestones a bit differently or adjust some of the existing mechanics there.
Will take a look at hubs as well.
Other languages are definitely planned, but it only makes sense once the game is mostly in a finished state.
