Quite an impressive and fluid system of combat that I'd like to see and play more of. However I really couldn't see enough of the action at the beginning, so I found it very hard to progress. Maybe increase that radial lantern at the start, just so your players can get a feel for the game first before the challenge of limited view - try to ease the player into the experience a bit more.
There were a lot of enemies in a small area, so maybe space them out a little at the start just so I can try all the different skills and see which one I think works best for how many enemies are on screen.
I think you've got a good core game here, it just needs to have more of a difficulty curve to teach the player.
