This was an interesting tactics game premise. Makes me think of Pyre. I wish that the teams had different colors to make it clear whose team was whose. I thought that the heat/cold mechanic was interesting, but could have been explained a bit better. But hey, limited time.
Overall, outside of those nitpicks, this was a cool concept. I can imagine a simpler tutorial mission with fewer characters, but boy do I know how hard AI can be. Good work!
