I liked this game and where I do have some cons, I have many pros. I'll be comparing it to Bo Wei's work just to let you know.
Pros
I love the setting, story, and music! The creepy but classy music mixed with my traveling with what really feels like a Poe book is so nice. Katrina is pretty sexy and I do enjoy her, and Death did get a chuckle out of me making me look forward to other characters in the future.
Cons
Now my cons...let's see...first person, as I do like it since it's unique for you game it's just to close! It doesn't allow me to really enjoy Katrina body like ToT, and Mix Fight does. Mix Fight goes with a partial third person view and I think that's a better feel for this game. I haven't beat Katrina yet maybe I suck, lol. The combat is nice but I feel is a bit to hard for me if this is the first boss out of 13. Oh! The 13 doors...yeah right now is fine but you are going to need to change it later in my opinion, in late game it's going to be to much because you'll be counting doors to find the right one, I'd get maybe a larger area and spread them a bit so not to get confused, just me.
Katrina as cute as she is kinda fails in one area, I don't know 100% were but in my opinion I think it's "size" no not body shape, lol. In Bo Wei's works one thing I can say he does great is making all his women feeling larger then life goddesses, even Lily feels bigger then Katrina maybe look into that. Last, more story! One thing I liked more then Bo's work is the story driven pull of the game at the start, made me feel I had more of a connection then being just the next boy dominated. Katrina teasing to keep me forever and the choices of words made me very pleased. I'd personally like more story and stages of training like in ToT, but with more bad endings~ So far ToT only has two real "bad" endings and it makes me sad I don't have more of a I could be the pet forever to this or that person. Cobra my favorite damn it, and I get no bad end!....
ANYWAYS~ Love the game so far and keep up the good work! Sorry if my thoughts are everywhere first review ever lol.
