I forgot to move last night. Kn-10
I do worry about the fire demon for a couple of reasons:1) except for the king (and now the lion), I've tried to remain faithful to the original pieces as much as possible. The more I change, the more it bothers me that this isn't a true 1D adaptation. 2) The cramped quarters of this game make the fire demon far too powerful. In Tenjiku shogi pieces are completely removed, and there are pieces to spare, but in Ito Shogi, there is a small number, and either it will capture too many and add them to that player's arsenal, or it will completely destroy them, reducing armies to nothing very fast. I have worked to try to limit the powerful pieces because I want this to be a game of combinations and tactics. I'd worry about such a powerful piece reducing rather than enhancing the game's complexity.
That said, I agree that it might be good to have multiple variants with different degrees of power in the pieces. Not so powerful as the fire demon, mind you, but nevertheless, one could probably have an interesting game with more exotic pieces or a game with more stepping pieces. It'd be good to play with ideas. We'll see.
