Hollow Knight
The idea that made the creators want to create Hollow Knight started in a game jam, Ludum Dare 2013, in which two of the game's developers, Ari Gibson and William Pellen, made a game called Hungry Knight, in which the character that would later become the Knight kills bugs to stave off starvation. The game, thought to be "not very good", used to hold a 1/5 star rating on Newgrounds but has since increased to 4/5. The developers decided to work on another game jam with the theme "Beneath the Surface", but could not complete on time. However, this gave them the idea to create a game with an underground setting, a "deep, old kingdom", and insects.
