Hollow Knight
To create the game's art, Gibson's hand-drawn sketches were scanned directly into the game engine, creating a "vivid sense of place". The developers decided to "keep it simple" in order to stop the development time from becoming very long. The complexity of the world was based on Metroid, which allows players to become lost, focusing on the enjoyment of finding one's way. Only basic signs are placed throughout the world to direct players to important locations. The biggest design challenge for the game was creating the mapping system and finding a balance between not divulging the world's secrets while not being too player-unfriendly.
