Thank you for your feedback and kind words. As to your bugs;
- The save button vanishing is a known issue and will be fixed in the patch I'm working on now.
- The examine self button was stubbed in early, so it doesn't have much meat to it yet, but I am working on implementation later on
- The book, as noted in several comments, is the hardest thing to deduce, as it's basically trial and error / moon logic. The next patch will have a bit more optional guidance for players that should alleviate things a bit.
Thanks again for the reply, it is very much appreciated.
