Very nice graphics as others have commented very reminiscent of Castlevania, also i'd say Altered Beast and the a dozen other cool retro games of the top off my head. Character is very badass looking anime type as well which is cool.
The only bad mechanics i can bring up are the fighting which is a a bit busted also another bug someone mentioned i got knocked out level by a flying monk as well :(
I like your level layouts though very cool columns with overgrowth you have to jump across etc and as i mentioned most of the art is stunning.
Your story seemed very cool and mysterious as well.
Very interesting unique game so well done
P.S I'll have to try again at some stage to get past the flying monk part at some stage :) A save spot/starting point at the church would be nice to add maybe.
