I wasn't playing the game when they released the Senkaimon Tower, so this is my first time playing it. And I'm completely in love with this mode, I like this kind of stuff SO MUCH, I'm feeling like playing Dark Cloud with the floor restrictions or the Cave of Ordeals from Twilight Princess. It's so exciting, I'm at level 35 right now, don't know if I'll be able to complete every floor, but I'm having a blast.
Also, I got Kaien from today's free summon, yey! And congrats for getting Kisuke, Uthred!
