In anticipation of the upcoming (small-ish) 0.5.1 update, the Patreon Guide for the full 0.5/0.5a. It contains some spoilers but isn't a complete "tell you everything" document. It's in PDF format.

Thank you for playing the game and continuing to enjoy the madness within my mind.

I'm expecting the 0.5.1 to be out for patrons/supporters by the end of May, and possibly out for public release by then as well, depending.
