I didn't have any problem completing it, just had to go around to where the curious people were. I like the mechanic of harvesting energy to do things - clever.
Would be interesting if, when harvesting an emotion, the harvest target would say something related to that emotion. For example, "There are monsters around, but I'm not scared" when you harvest courage. Would just make it feel more thematic instead of just generic energy and give a little something to read while the bar fills.
I did find several areas where enemies will just get stuck, like in this screenshot I was able to beat on them without any repercussion.
Well done!
