I am reporting a problem with the Japanese display.
The first display bug is the bug/feedback report button in the upper right corner when you start the game.
(See the first picture.)
If the button could be extended horizontally, it would be possible to display "フィードバックまたはバグの報告" without any problems.
(If the English version also seems to omit the display in the middle, it should be fine.)
Next, when you interrupt the game by pressing the Esc key.
If you try to display the Japanese "ゲーム" vertically, the "ー" is forced to be horizontal, so the display is not correct.
(see second picture).
Although it may be a bit arithmetical, replacing "ー" with "|" may make the display a little better.
Alternatively, it may be better to rotate only the "ー" by 90 degrees.
Removing the Japanese word "ゲームの" would also be a good idea.
(In Japanese, "一時停止" alone makes sense.)
