Darkness Hour is a time-based action platformer. The player's objective is to collect the required number of butterflies before nightfall. Each level contains a limited supply of keys needed to unlock doors. Some doors lead to dead ends, and using keys incorrectly results in a game over. If the time limit expires, the game ends immediately, regardless of remaining lives. The game includes three levels with teleportation points that move the player to different sections of the maze. Enemies resembling shamans can be defeated with an unlimited supply of throwing knives, while touching them or coming into contact with sharp spikes results in instant death.
