Those of you who have been looking forward to seeing more from Ninjala will have to wait as the game has officially been pushed back to 2020. GungHo Entertainment released a short notice letting fans know of the circumstances, which according to them will be "to implement improvements and polish the game for final release."
They also released a video about the development, which you can watch below. We actually played this game back at PAX West last year and had some fun with it, but it reminded us a lot of Splatoon in various ways. We'll see what they decide to improve sometime in 2020.
