What an interesting concept. I really like this. It encourages a lot of experimentation and creativity combined with strategic placement. The art was also fantastic. Very nice looking and cohesive style. The effects were also great. I do think there is some balancing to do, but that only makes sense with a 1 week jam. Something I wasn't sure of was how the storms would arrive. Was it based on number of cards played or was it a timing thing?
Either way, I really enjoyed it, and played it a bunch of times.
