Damn that's brutal! Wait, so am I just beating all the difficulties on story mode? I tried a Master ninja mission, I was able to beat #3 with a random partner.
I really enjoyed it but I do like puzzle games myself. I wouldn't say it overrated by not a 10 or 9 by any means. I'd say give it a try on sub account and see if you like it.
Well.. pro tips? I found myself relying on the Eclipse Scythe the moment I got it and leveled it as fast as I could for max damage. I read the trophy guide, but it isn't all informational.
