グラディウスシリーすの最高傑作とも言われる。
確かに面白い。
前作のグラディウス（アーケード版）よりだいぶボリュームがあり、難易度も高い。
普通の人がギリギリクリアできるぐらいの難易度だと思う。
Translated with ChatGPT4.0 Gradius II (Switch Arcade Archives)
It's often called the masterpiece of the Gradius series.
Indeed, it is interesting.
It has much more content and a higher difficulty level than the previous game, Gradius (arcade version).
I think the difficulty is just on the edge of what an average person might be able to clear.
