The graphics and music were nice but there were some problems.
Your hitbox is a bit vague with your ghostly form and some of the jumps were unforgiving.
I had several instances of enemies going through walls but there is a bigger problem
The controls aren't mentiones anywhere, I had to fumble about to find that A was the action key and I suspect most players wouldn't figure out that you can curve the motion of your sword with up and down.
Otherwise really good!
