As the genre's name suggests, Metroidvanias like Biomorph are largely descended from two games: Metroid and Castlevania. In recent years, however, games from the genre have increasingly taken inspiration from FromSoftware's iconic Souls games, particularly regarding difficulty and death mechanics. In fact, games like Hollow Knight and Salt and Sanctuary are filed under the Soulslike category just as often as Metroidvania. Even Star Wars Jedi: Survivor has benefited by blending Metroidvania staples such as ability gating alongside a Souls-style combat system.
