First off - good job on finishing!
Now, there are few things that need a really small upgrade that would make a large difference. Feedback, add feedback everywhere, I didn't know when I was hit or when I was hitting an enemy.
Another thing is, currently there is no way of attacking down or up.
The game is too hard and seems really long, I couldn't really finish it.
These are all quick and easy fixes. Don't take this comment as rude, I am just trying to give constructive feedback.
On the other hand art in this game is really good and the audio is really not bad.
Hope this helps.
Keep it up!
