The turrets seem to take damage, but I can't bring them down. I guess that was intentional? I really enjoyed the voice acting and the music. Generally, the content looks very nice.
Not so sure about the gameplay, I don't think I ever needed to roll. And the floor panels "on fire" seem a bit to obvious. But the magic system is a very cool idea. Its used to increase damage, but it could be used to unlock doors. I think you wanted to aim for that direction, given the fact that you can remove the runes.
