Yes, I know. Pretty hilarious you already found out one can just pass through. Gate opening was done on the last couple hours...
But yeah the animations are mixamo 3d mocaps. irl movement is slow for combat. It was my first time doing such a game so I was just learning most stuff. The NPC was supposed to have voice lines but I got the voice lines last day. Too little time to implement. The menu was more like developer debug menu to enter the scene fast. It probably should just have been a new game menu in the end. But I am glad I learned a lot and I am implementing a better combat system now faster animation, dodge mechanics etc.
