It seems the folks who hired you to farm this barren, lifeless rock forgot to mention the skeletons, zombies, and exploding ghosts who like to come out at night and make your life a living hell. At least they gave you this grenade launcher.
In New World, an action-packed farming sim by Louissi, you use the [arrow] or [WASD] keys to move a Johnny Appleseed-like fellow along the circumference of your world, pressing [Z] to throw out seeds and eggs, and using your shovel to raise or lower the terrain in the best way to help your plants and animals flourish. But, when the sun goes down, the nasties come out and you'll need to trade your shovel for a shotgun or other heavy weapon to stay alive, picking up coins from your fallen enemies as you go.
When daylight comes, you can spend the overtime pay you earned blasting away the undead to buy seeds, eggs, ammo, and upgrades for your guns, health, and other abilities. By now your hard work is paying off and trees have sprouted along with the first signs of life. Later, when you have the money, you can unlock two other creatures for your eggs to evolve into.
One drawback for those that prefer the farming side of things, is how fast night comes and you have to pull out a machine gun before you can get back to tending your crops and cattle... though for those that prefer to run-and-gun, there is a special survival mode with no farming. Fortunately, its lovely artwork, retro sound effects, and multiple upgrade paths and weapon choices make this unique sim about space farming a clear winner.
