Check flashplayer update's. Try running different flash based apps to compare the performance and deduct if it's your end or GGs.
There has been a few bugs in GG recently but haven't heard any about slowing down.
And if I was to bet I'd say the same as Mr.jw, that the slower performance is caused by loading data for first time from Bleach Online, give it a day and should work swaggy.

After years of searching, i found Opera.
Only one that works.
Thanks for helping.
I think it's fixed already but I suggest you only use Opera for this game and use another browser for daily use. I personally do this as well and make sure you keep your browser in front of other programs else it doesn't attack
