Bloodstained: Ritual of The Night will be coming out sometime in 2018. Development seems to be nearing the end, and the developers are now asking for fan input on bonus lines and content they are interested in seeing. This is mainly in terms of Easter Eggs and such and not major changes.
They also noted they are accepting more than one submission, and all they ask is that the submissions be impressive to them.
They sent out the following tweet
English voice acting recording is about to begin! This is an open invitation for requests for bonus / Easter egg voice lines you would like characters to say when certain special in game conditions are met! Feel free to submit more than one request too! IMPRESS ME. pic.twitter.com/6Yf5xn2jGU

Will you submit an idea?
We will have a review of Bloodstained: Ritual of The Night when the game launches in 2018 (Disclaimer: This author was a backer of the kickstarter)
