Cool feel and good voice acting. The enemies look real cool as well, the spike shot has a nice glow in the darkness. The darkness is a little overwhelming, and neither of the light abilities showed a cooldown timer, which would have helped with planning their use. I also found it very difficult to tell when and why I was taking damage.
In the opening, the character steps on one of the little slugs, so I thought that was how to get rid of them, but I instead seemed to be taking damage from touching them. Other times it seemed I took damage when they touched one of the small lights I could summon. I think I may just have not understood the mechanics.
