It looks very nice, the visuals are pretty great and killing the enemies ( and even dieing sometimes xd) gives a pretty satisfying feeling with all those slashes and blood and so on. The only downs would probably be the fact that it's so difficult to move and control the character and maybe also the design a bit, but other than that, great job on your first project on NG! ;)
Only things I would suggest to improve would the the rensponsiveness of the character, more variety in design/enemies and maybe a highscore leaderboard.
