I really love how polished the game already is, especially from an animation and UX point of view. I struggled a LOT with the first boss though, it's painstakingly difficult for a tutorial level, even if you know the patterns... you really have to hope you can pass the "see if you can dodge this" phase with enough HP to survive the rest! I noticed in one of Rocc's first appearances, he's identified as Rocc and not "???". There's also a typo in "existence" in that scene:
Great work, and congratulations for doing it with Godot - really excited to see what comes next, and this will definitely become a quality target to meet for my own Godot games.
