pretty retarded. you cant get to the white without touching the blue so you get an immediate game over screen and then the back button doesn't work so you cant get back to the game.
i don't know what happened but on the last boss fight our swords clashed and were stuck for a sec and the he went flying and his arm was stuck outside the arena so he was only using 1 arm and he couldn't move. IDK if it was a glitch or not but it was cool
