Dragon Marked for Death was originally drafted by game designer Yoshihisa Tsuda as a PSP title, developer Inti Creates president Takuya Aizu revealed.

Aizu shared concept materials that date back to August 18, 2008. The materials label it a 2D side-scrolling action game in the vein of Mario and Mega Man, where players can enjoy exhilarating action, solving the mysteries of the story, and character growth in maximum four-player cooperative play.

Of course, Dragon Marked for Death is no longer a PSP title. After being officially announced for Switch in August 2017, it will finally launch worldwide on January 31, 2019. Here is an overview of the game and characters, via Inti Creates:
