right now I’m using the playdate default “A Button Held” timeout which is ~1 second. I agree it could be a bit shorter, I’ll just need to roll my own timer (as I do for the undo). I’ll look into it for an update!
Right now that’s intentional! I’m planning on adding an option for turning on/off the king rule but until that’s built I figured I’d err on the permissive side and let players restrict themselves for more of a challenge.
