The developers behind the intriguing Rainway application has announced that it is not in active development for the Nintendo Switch platform. The team says this is because they have not received approval from Nintendo to continue the project. Once Nintendo is onboard then development will presumably resume.
We are currently actively developing Rainway for Android and the Xbox One. The Switch is not in active development as we have not received approval from Nintendo to do so yet. When we have an update, one will be posted.
