Bloodstained will probably live forever in the memory of those who backed it on Kickstarter. It was part of the "actually creators can rebuke publishers and do their own thing" era of the crowdfunding platform, alongside of projects like Mighty No. 9 and Shenmue III.
That was back in 2015, and the project has made many twists and turns to get to the point where it is today, no matter how many platforms it left dead, dying, and bloodied along the way (RIP Vita and Wii U). Multiple developers have been involved in its creation at this point, and a new art style was unveiled just several months ago: which likely had a lot to do with the myriad delays the project has dealt with since its announcement.
Now, it's finally here.
