i playtest in the hardest difficulty and always try to get the top score to know that it is possible, but yeah, im thinking of toning it down in some levels like Courtyard and Checkpoint. I still want the hardest level to be a big challenge, but yeah... I think its the enemy count in a wide, hard to keep track of, area. The Bullet Time level has a lot of enemies but if the player does take time to think of a strategy and order of killing its a rather simple level to beat since they are confined in a small area , thus more predictable to manage
