Thank you for comment and actual run throught the game. I did couple conceptual mistakes, first of them using mouse as a controller for rune clicking, space would be enough, and a latency would be decreased and it will solve some common problems with graphic vs. audio perfomance. I'm awfull at UI building, but I'm working on it, maybe next time hopefully. I'm back to Unity and possibly will be back to Godot which has a cool UI. There is a way for improvement this battle system and I'm already working in it in Unity. Thank you again for playing.
