Did you unlock the full version?

Yeah

I would comment on the move notation style.
In shogi (as well as bigger ones) moves numeration stands that like: 1. move of Sente 2. move of Gote 3. move of Sente, etc.
Unlike chess, where one move contains both white's and black's moves.

I agree but going like chess-style would make pre-moving and fitting easier because dai dai shogi would easily go over 400 moves per player…
