Thank you very much for the feedback. Both the bug of the arrow jumping when it shouldn't and the bug of finishing pressing the key at the end of the timer only appeared for me a few days ago, so I'm already fixing them.
The upward jump only appears when she's grabbing the edges, because she gets the wall jump further forward and it was causing a conflict between the buttons, but I intend to adjust that. I didn't get to see Slato parrying with the up button, but I'll investigate.
I will make it possible for the player to choose whether or not they want these minigames before the bosses and saves, thus preventing frustration for those who don't want to go through that.
