Easy at some parts, hard at others... I love it all!!
My favorite was the lv 19, I spend a lot of time to do that right, and a lot of time doing again and again, just for fun =D
BTW, I think the Super Slash Medal isn't working... I get a 37 and I don't get the NG medal ._.
I've post my 37 hit in row in my page, look it '-'
Anyway, Keep up the good work
