Well I was too hasty, now the game is barely beatable, it's too hard now. Any time the thread is going to touch scissors it's instant game over, there shoulde be a treshold for instant game over it's first thing that comes to mind, there a lot of obvious ideas but I didn't had enough time, so it's pretty bad. Any boosting can accidentaly make thread be touched by scissors, any touch by fighter when boosting deprives player's HP, so it's hard.
