This is a good idea for a game. I found it a bit hard to learn the cause-and-effect of the lightning bolts at first though. If I understand it correctly, the lightning strikes at the beginning of the next turn before anyone moves, rather than the end of the turn after everyone has moved. Having the time distance between action and effect meant it took a while for me to figure out the mechanic. Good job at making the game ramp up though and introduce the mechanics step-by-step.
