Glad you enjoyed it! We had grand goals of a system where you could send multiple fleets out to planets, managing the flight time it'd take them to get there vs. time before you'd lose conquered ground. With this setup, you'd opt to manually control certain fleets on sectors or have fleets settle the outcome of battles themselves - to give you more time to strategically conquer the galaxy in time. (Including even smaller scale battle control, via units on the ground level)
We weren't able to satisfyingly implement that within the time in the end, so what you see is pieces of a grander concept! Thanks again for your feedback :)
