I think same enemy in Part 1 is here again. In Part 4 it have Death skill I won't try get risk to them but if have lucky evade Death skill sugarcube. And time played it almost reach 35 Hours in total. I didn't think I can play lower 35 Hours (If I note all Strange Medal location and other more secret) I'm not sure about secret boss, what skill it cast to attack. I'll find on off-screen then. Because I could put in longplay instead sugarcube.
