Bloodstained: Ritual of the Night on Switch is certainly playable, but it's the roughest version of all the releases. In an interview with GameDaily, Koji Igarashi explains that the team is working hard to set things right, and also explains how the development of a Switch version prevented unique challenges. Check out Igarashi's statement below.
“Despite our best efforts to optimize Bloodstained for Nintendo Switch, development for this platform came with issues we did not anticipate. We are entirely focused on delivering a fix as soon as possible, through a series of patches, and achieving parity on Nintendo Switch is [a] priority.
Development for Bloodstained began following the successful completion of our Kickstarter campaign in 2015, originally planned for Nintendo’s Wii U. In 2017, deep into our development timeline, Nintendo debuted the Switch and shortly thereafter announced support for Wii U would be discontinued. The introduction of Switch and the shift from Wii U to a brand new gaming platform created a new frontier for our development team to explore and tackle. We are looking forward to sharing more detail on the upcoming fixes to Nintendo Switch soon.”
