Castlevania producer Koji Igarashi has been spending the past couple weeks distracted by the same thing I’m playing: Super Mario Maker. Polygon asked him to make a level and we got to see how he messes with the player’s expectations. This level isn’t open to the public, but IGA has been hard at work uploading even more creative levels for all to play. He’s working on a faithful recreation of Rondo of Blood with creative use of stacked enemies.
