Well, Hideki Kamiya reported his statements on the matter via Twitter, beginning with this:
"As you may have already heard, Scalebound has unfortunately been canceled. I'm very sorry to everyone who was looking forward to this game."
Followed by this:
"Sorry to bring you such bad news at the start of the year. All I can do for you is to promise to keep delivering fun games."
"I'll work extra hard to never have to let you down like this again, so I hope you will keep watching over us in the future too."
"And...I took time off for my mental health?
And finally this:
"I thought I would get lots of savage messages, but in reality I'm getting lots of warm messages. Thank you.
He is such an honest, sincere, and lovable guy. I'm glad he is getting the rest he needs. Mental health really is important, and the cancellation of Scalebound must have hit him hard.
No worries, we have your back, Kamiya.
