The Tree quest and the doublehorn quests are not yet available but will be at the next public build launch! The number of quests available for this version was deliberately low, because I wanted to work out all the kinks first and didn't want too much investment in this build, as the next build may not be able to use the saved games for this one due to revamped content suggested by Patreon supporters. (All saved games should work for all versions starting from the upcoming one, though!)
