Only Skeleton bandits side quest arc left to finish although, again, some side quests will continue to be added. I have a few planned.
But once skeleton bandits quest is done, the game will receive very little updates overall. After the end of 2021, no further updates will be released unless it's bug fixes.
What has been added:
1. A side quest arc “Revenge of the witch ghost” is finally completed in this patch. The outcome of this quest alters a lot of things on Alcella island.
2. Luca’s profile added to extra menu.
3. A side quest “Messy cleanup” added.
