Thank you! Our main programmer outdid himself when it comes to feedback and responsiveness.
We initially planned for more attacks, for example one where the boss would submerge into the mist and then spawn burrowed tentacles that would start following you. These were excluded because in the last 6 hours we didn't have the AI and we were still making boss attacks.
For the bug, yeah, we did not find a good solution to that, although deactivating its colliders when it starts the recover animation seems like one, that brings some design problems too. Hope that helps clarify! :D
