Before Dark is a time-race platformer where your character can die if they stay too long in a level, and also they cannot jump and hence need to use the environment to reach places.
In Before Dark, you have to pass many areas in order to reach Neon's family place. It is a dangerous road, too difficult to master yet easy to figure out. Each level is drawn with love and made to be difficult enough to not be impossible.
The platforming part of the game is quite interesting too, since Neon is a ball that cannot jump, he has to make use of his speed and rolling against walls.
