I actually haven't played any Puyo Puyo games before this one, and I just started playing this one a couple days ago. I ended up really liking it so I googled for a translation.
I was filled with joy when I found this.
I've owned both iPhone and Androids over the years. Both are just as good, other than Apples higher price. I'm currently on Android, Samsung S21 I think, and very happy with it.
