Since people are spending more time in the sub-1000 sector maps than I had expected, I've decided to redo most of those maps to make them more interesting.
Originally the maps below sector 500 were just made from 2 rooms, which makes them quite easy but also means they lack the variety that later maps have.
Now the sectors from 0 to 999 range from the original 2 rooms up to 3, 4 and 5 rooms, which allows for more diversity in map architecture. Also means that they're a bit trickier, but they're worth more reward too, and with the changes made in the 1.1.0 update players shouldn't find them too difficult.
I hope you enjoy the new maps.
