When you made the Penumbra game, did you by any chance take inspiration from the Penumbra series such as Overture?
Had no idea they even existed until someone pointed out the name and similar beginning. The only Amnesia I ever played was the one made by The Chinese Room called Amnesia: A Machine for Pigs. The idea of having the pillar underground was inspired by 2001: A Space Odyssey. The name came from a famicon design by Dylan Wells that I loved.
