It's funny Nutaku FKG run smooth when I play with puffin on phone, but super laggy on PC.
And both device use same internet. Maybe Nutaku FKG don't like intel CPU or something hahahaha.
I'm sitting at around 7m. I didn't amp my girls much, until now I only full amp 1 girl after start on Febuary.
And I quite lucky to get a lot of potential girls in first month.
So when those girls are ready to go I just use gold only for building new 6* I got.
On DMM I just broke my gems to run MoriMori during gold campaign.
I do lose a lot of gems, but since we get gems easy so no big deal.
