Inti Creates, the Japanese studio known for Mega Man 9, Mega Man 10 and their own franchise Azure Striker Gunvolt, is not involved in the main development of Bloodstained: Ritual of the Night anymore. Koji Igarashi's studio, ArtPlay, has teamed up with DICO and Monobit to finish the game as was announced in November 2016.
Inti Creates is still working with ArtPlay, but only for the development a prequel mini-game. To clarify the situation, the community manager of the game took to the official forums:
"Maybe it is best to clarify it here. Inti Creates is not involved in the main development of the Bloodstained game, but they are involved in the prequel mini-game. Part of the vagueness is to avoid unneeded attention and negative speculation. So yes, they are involved but not in the main game since last year's E3. DICO has picked up the development from where they have left off under mutual agreement.
"A lot of parties are involved so it could be quite confusing. ArtPlay is the main developer, while we are hiring DICO as a third party developer. We created the game design, story, direction, gimmicks, and the overall production of the game while DICO creates art assets, design levels, and basically filling in the manpower ArtPlay doesn't have. In the future, you'll most likely see 505 Games and ArtPlay credited on trailer videos and articles to come out."
Bloodstained is still quite far away as it is scheduled for the second quarter of 2018.
