Does anyone else get confused by some of the objectives?
A number of times I've been caught out thinking the objective was to get the bar high and keep the little virtual people very happy, and all of a sudden "LOST!!" appears. A few times it's left me a bit puzzled about what he objective was supposed to have been.
