小さなはさみ将棋

Description: This game is like a smaller version of scissors shogi. Unlike regular scissors shogi, pieces can be moved not only horizontally but also vertically. Also, when you sandwich an opponent's piece, it's not removed from the board, but is flipped over and becomes your own piece. The player who reduces the enemy's pieces to one or less wins.
In regular scissors shogi, you can only capture enemy pieces in the corners by surrounding them, but in this game, if you block the destination of an enemy corner piece with your own pieces so that it cannot move vertically or horizontally, you can consider it sandwiched and make it your own piece.
Let's say the first player's pieces are ◉ and the second player's pieces are ◎.
For example, if the situation below is the first player's turn,
◎▢◎◎
◎▢▢▢
◉◉▢▢
▢▢◉◉

If you move the piece two spaces below and one space to the right of the upper left corner to the top,
◎◉◎◎
◎▢▢▢
◉▢▢▢
▢▢◉◉

As shown below, you can make the enemy piece in the upper left corner your own along with the piece below it.
◉◉◎◎

▢▢◉◉

However, if Black then moves the piece in the upper right corner to the lower left corner, all four of White's pieces will become Black's, so be careful.

Then, during the first player's turn, from the state shown below, move the cursor to the bottom right corner as shown below.

By moving the first player's piece two spaces to the left, all of the second player's pieces become first players. In other words, the outer squares are connected in a ring, and if there are consecutive enemy pieces within the ring, you can sandwich them on either side with your pieces to turn the enemy pieces into your own.
You can choose between player vs. PC mode (player first or PC first) and player vs. player mode.
In human vs. PC mode, you can choose the depth of exploration your PCs will go into.
