I'm in a blunt mood tonight so sorry, but this was a bit annoying to play!
However, there is a lot good. The concept is very cool. The graphics fit and the floating roll of loo paper? is a lovely fun touch. In fact there is so much good here like the lights off, the radar, etc, etc.
It's just that overall it feels like too much all at once. I think this needs to start simple, and build up. Only one or two rocks on the radar, player dodges, the power goes out, they have time to figure out the lights, then we get going again, then the rocks increase, something else goes, etc. etc.
Or maybe I'm just old and slow!
