Hey, thanks for the reply!
1) Staff is definitely much stronger than others, that's why I have it off in its own little section on the side. The staff is really only there for fun right now, it's not meant to be balanced with the other weapons.
2) I could add some sort of full screen damage effect to indicate when the player is hit, I suppose, but between knockback and the blue blood droplets I'm not sure how much more I can do with this. When I start putting in sound effects it will probably help, too.
3) Difficulty is really high right now, handling multiple enemies is tough even for me, and I've played this game more than anyone! I'll work on balancing this out later, probably with higher health amounts for the player and more options for dealing damage.
4) You can definitely outrun enemies and reach the end of the prototype. Once I start adding in win conditions and goals aside from simply "reach the end" this will hopefully be less of a problem. I have plans for more interesting systems of character progression, and enemies will drop cool items so hopefully the player won't want to skip them and rush to the end
