I had forgotten about the English patch, and didn't notice when the patch was installed. So imagine my surprise when I went to play last night and the game was in English! It seems so weird for most things to be in English, considering I've only played the Japanese arcade version and this Switch version.
I bought the Studio Ghibli DLC pack, now they need to add a video-game song DLC pack; the arcade game I've played, Taiko no Tatsujin 9, has some great game music (Zelda, Super Mario Bros., OutRun, iDOLM@STER)) , but I'm not really liking any of the game music in this one except Kirby.
