I hoped for ...
At first I had the feeling of a Castlevania clone, and I was somehow excited but I realized it was not what I expected. The game needs improvement on many points.
Graphics : Graphics were okay. Even if you don't want to graphically improve them, I suggest to add a little bit more animation at least instead of enemies froating weirdly everywhere.
Style : For the feeling you tried to give to your game. Seemed to me like a mix of Castlevania and Prince of Persia (old games) so you got a nice score there.
Sounds : No music, only sound effects, barely enough if you ask me.
Iteractivity : Control are ok. Nothing awesome and they are strangely placed. Ctrl or Shift could be an option or any other adjacent keys.
Overall you got a 6 which leaves place to improvement a lot but still there is a great potential in your work. You might want to review your difficulty level tho.
