A couple more pieces of feedback:
The frequency and duration of the lightning strikes is PERFECT! I love that I see them but I find myself not ever feeling spoiled (much) by them.
The torch placement would be nice to be a little less random. I had a couple floors where all 3 were right next to each other.
The last thing is the score counting upwards... score generally means more is better. If a better performance means lower 'score', then maybe 'time' is a better word to use.
