I lasted 30 minutes. My head started to hurt. IT WAS TOO MUCH FOR ME. ugh my head is hurting just thinking about it.
I also tried beating Ran with Marisa....and failed. I beat her with Sakuya and Reimu ( both of their spellcards ) and it was pretty simple. But when it comes to Marisa, I suck. Too hard to control! >:U I'll just keep practicing.
