It looks like a good start and well thought out in several areas. Some improvements could be the following:
1: Being able to turn without actually moving. - Without this, the player can get stuck between enemies and not be able to fight back.
2:Free movement while attacking and free attacking while walking. This would help the game feel smooth.
3:Add music. Music sets the mood.
4:Restrict movement to moment of keyinput only. - The extra steps that happen without keypresses is not good.
Otherwise, the visuals are nice and the layout of the entire game such as the menu provides some nice options.
