I'll share some feedback after my first steps in the game :))
However, regarding the FAQ, I find a floating adaptable FAQ similar to the one in Ecency very useful. It shows different content based on your device and site you're at, so it seems simplier and more relevant than a common FAQ website with detailed description of game mechanics (in case of Holozing), formulas, and so. People will eventually end up browsing the details, but just to get the essential information, this one works.
