Thank you for trying it out! As I mentioned in earlier comments, people have asked me several times to make the ai more difficult, it seems I went overboard this time. Someone suggested to add a difficulty level, I'll do that.
As for the UI feedback, it doesn't mean that the move is executed if the ui button is highlighted, but rather, it just means you are pressing. The move will execute when the player has or recovers control. In your case, it might be that you got hit and have not recovered yet but are pressing a button like block.
I understand it might be overwhelming now, as a new player with the new difficulty. I apologize. I'm adding the difficulty level and a tutorial/training mode so that people aren't surprised with a beatdown, and end up raging.
