Did not expect this to be this good but upgrades and player power progression made me want to play more even if gameplay otherwise stayed more or less the same.
Didn't really use rolling as most attacks were well telegraphed and I gained enough speed to just pass aside.
Playing in non-full screen mode not everything fits in the window because of Unity's WebGL bar that lest you go full screen. You might want to add some 60 pixels to wondow height.
