Maybe putting that big level 794 part in the start isn't necessary;
You could use the more common survival difficulties, like this one;
Maybe a bit more description would be good, with an optional image;
Say a bit more about the entities, colonies and outposts, rooms (if any), events/incidents (if any), do's and don'ts (optional), and how you could enter and exit;
I did a basic guide to make levels, you can find it here.
