The planet you landed on is a desert planet without grass. Grass sprites are replaced by sand and dirt sprites.
Small changes concerning balance, gameplay, or graphics.
a lot of repetition in Alien lands, biomes, not as something to do so if the desert had a lot, or other location, too many at 4000 cells and more.. and a lot of repetition of the lands. very often, even if you put small generation

Should look better now with Alien Biomes.
