This is a really funny idea, and the environment is a pretty cool blend of Minecraft and DS3. But the controls are really clunky, and if feels really strange how locking onto an enemy doesn't lock the camera rotation.
The attack has a really short reach. Even if the animation looks like that, the hitbox could have extended further. The lack of a heavy attack is not really an issue, but I find rolling difficult. This may be a result of me not being good with gaming on a keyboard, but rolling is such an important part of Dark Souls combat, I think it should have been the left click or space. I think jumping is pretty unnecessary.
