Thanks for giving it a try and for the feedback! The energy bar (yellow) was supposed to indicate who went next, but we realized later that most of them are set to the same speed, so it's hard to predict. Something we'll definitely fix. 

We set out with the aim of making it difficult, but lacked time to properly balance it, so I doubt anyone will make it through without having exceptional luck. I think the furthest anyone has gotten is 5 battles, and that's after a few playthroughs.
