Playing on the mac port, so it's slightly more updated, here's a handy dandy little report!
-During the princess questline it gets stuck on "build a Furnace" until you've fully built the castle for her
-While exploring the map, I found exactly ONE black, untextured tile near the fork just before the waterfall and the Cultist?
-After finishing the slime section of the Cultist? quest where you learn her name, at the end of her dialogue when you press E, her name disappears but the rest of the text box remains. Once you press E again it'll make the text box go away. The next time you speak to her, her name is filled in, but this is repeatable
-As has been said, a compass/map would be great, and I'd also really jive with a way to change how zoomed in you are on the player
With all that being said, this is a PHENOMENAL start to what I can only hope will become a full game in the future. Tally Ho!
