Very cool. If these guys are smart, they'll start the Kickstarter on the first of October and let it run through Halloween, capitalizing on a time of year where I'd wager many people revisit the Castlevania series. I know I do. In fact, Konami themselves may do the same, Nintendo permitting, re-releasing the GBA games or SNES Dracula X through the Wii U Virtual Console.
I'm assuming this might be something Inti Creates might be working on with Igarashi. If true, that'd be a great opportunity to do something like they did with Gunvolt. Maybe we'll have a CastleMania that is a Metroidvania game and an NES styled platformer to coincide with the release. Through Beck in there for the heck of it and call it Mighty Castlemania.
