Went through the tutorial and found some spelling/grammar errors. Some are minor but can use a little clarity.

I've highlighted the changes.
In the "Rotate the camera" section: "The next step is to rotate and tilt the camera, do this by holding down the 'MIDDLE MOUSE BUTTON' and draging the mouse around on the screen."
Should be changed to: "The next step is to rotate and tilt the camera
. Do this by holding down the 'MIDDLE MOUSE BUTTON' and
dragging the mouse around on the screen."
In the "Time to mine" section: "Mine out a 3x3 room next to my room and let your imps claim the area, do this by left-clicking on the tiles that are flashing with the pickaxe tool."
Should be changed to: "Mine out a 3x3 room next to my room and let your imps claim the area
. Do this by left-clicking on the tiles that are flashing with the pickaxe tool."
In the "Build bedrooms" section: "All creatures in your dungeon needs sleep, make them a bedroom with the size 3x3 in the newly excavated area."
Should be changed to: "All creatures in your dungeon
need sleep
. Make them a bedroom with the size 3x3 in the newly excavated area."
In the "Build beds" section: "Now build beds for the imps, orcs, and the piggehs, do this by right-clicking in the bedroom and selecting the beds. You will notice that the imp bed requires rope and wood, these can both be harvests from the roots sticking out of the dirt blocks in the dungeon."
Should be changed to: "Now build beds for the imps, orcs, and the piggehs

. These can both be
harvested from the roots sticking out of the dirt blocks in the dungeon."
In the "Time to farm" section: "Next up we need antroots, these grows in the farmland. Build a farm room and a 2x2 farmland inside it."

In the "Baking bread" section: "The food will not last forever, build a cookery room with a baking table inside it."

In the "Keep your minions drunk" section: "Now you seem to get a hang of it, now you know how to produce creatures and how to keep them well rested and well feed. But the orcs requires beer as well to be happy, build them a brewing vat in the cookery room."
Should be changed to: "
You seem to be getting the hang of it
. Now you know how to produce creatures and how to keep them well rested and well
fed. But the orcs
require beer as well to be happy
. Build them a brewing vat in the cookery room."
In the "Kill the humans" section: "Nice job, now all that is left is for you to kill the humans. I have marked out the area leading to them, and don't forget to use the rally flag to call your army to that location."
Should be changed to "Nice job

. Don't forget to use the rally flag to call your army to that location."
