Hello!
Content is definitely light at the moment. I've put adding more content on the backburner while I finish up many of the features and gameplay mechanics on my list of to-do's. I try to sneak in content here and there as much as possible. The reason I don't go hog wild on adding content is because it's really tough for me to test the game after I add new mechanics/features when there's a ton of content.
The good news is that I'm starting to focus on content now that I've recently finished a lot of features I had yet to add. Namely, more events, stuff to build, and underground things to find will be a priority. :)
