Oh, huh... Well, I have to say: I know about Shogi, but never played it. ^^'
Thanks to your comment, I dug around the games that inspired me for the jam, and they are themselves inspired by Shogi!
So it is not intentional on my part, but my game indeed has a lot in common with it, that's cool!
Other commenters have asked for a bigger board too, so I guess there really is something to do in that direction, I'll have to think about it.
Local multiplayer is coming after the jam! It was initially intended, but I put it aside since I figured most testers would be playing solo. The code is already made for it, it just needs concrete implementation =)
