I am always glad for feedback on anything and everything. Of course, I would prefer it to be constructive. If you have any issues with the book or the website or anything else, let me know! I’ll do what I can to fix it.
As far as the book goes, I know that it’s not perfect. Fact is, it’s still in the testing stage. This is the equivalent of Unearthed Arcana right now. It’s been reviewed enough to be released to the public, and is polished enough to be worth the charge, but is still open to change. It’s why there’s not a hardcopy of the book right now. I fully expect it to undergo many changes over the next few months, or even year or two. But hopefully we can work together to make the book an a refined and excellent source of fun for all of us!
