Thanks! Really glad you like it! Awesome to hear that it will be used for some actual games! I will look into the tag thing, I tried to put it back in another category, maybe that helped?
I was planning to compose some music and add some effect, but my scatterbrain started working on other things :S I might come back to it though - sound would be really nice.
Death animation I did consider, but I personally have a couple of cards that prevents me from dying, even below zero life, so I left out that feature - the original plan was to have stages of the avatars depending on how much damage they had taken, but reading your comment, maybe I should reconsider.
