This looks brilliant. I love the Curse of the Moon style, and how well you've incorporated old enemy sprites into it.
I do have to mention a concern though: Konami absolutely adores owning the Castlevania brand for the singular purpose of not allowing anyone to do anything with it because everything they do they do to spite their customers.
Maybe it would be a good idea to take the video down to avoid getting a Cease & Desist notice from them? I doubt they're as nice as Nintendo who at least let DoctorN64 finish AM2R before they had him pull it down from his site.
Hello, dude! I'm this project's co-director and am responding on behalf of the team. I see this is your first post here, welcome to the Dungeon!
We understand the perceived risk of keeping the video up, but it serves two purposes that the previous version of this project lacked:
1-Exposure to attempt getting future help from other artists/coders if the necessity presents itself.
2-Makes us transparent in the eyes of the big guys. We are not interested in taking a million steps to hide, just to be cancelled suddenly and summarily.
We are and have always been sharply aware of the possibility of the C&D, not once has this escaped our thoughts, and anyone believing we are unaware is misjudging our intelligence. The possibility is also why we aim to gain no profit from the project, and all assets are made from scratch, not ripped. We could lose the project and still utilize the assets elsewhere - nobody owns a single pixel we made but us.
The logic that "hiding" will help avoiding a C&D assumes that a given company, with millions of dollars and employees paid to keep an eye on internet movement, is not aware of fans' utilization of their IP. They are. There is no hiding.
