This was posted in the OT, but it probably deserves a new thread I imagine, since many people were interested in getting that version of the game. People have already reported on how Bloodstained's Switch port is... sub-optimal, to say the least. The developers have addressed the port in question in a new Kickstarter post (as well as a Twitter thread), and the plan for improving it.
We have been listening to the feedback regarding Switch performance. Our goal is for everyone, regardless of platform, to be able to enjoy the game and have it run smoothly. We want to live up to your, and our, expectations.
Throughout the QA process we have been addressing performance issues in the game. Update 1.01 was published to Switch prior to launch to add content and improve performance. It did not accomplish as much as we had hoped and we need to do more.
To address the concerns brought up by the community we are immediately shifting resources to improve performance and stability for the Switch. You can expect a number of small updates that will improve different areas of the game rather than waiting longer for one big update. We will have more details as we dive into the work.
We thank you for your patience and apologize for the inconvenience.
