I love it! I ended up playing through it until I got all 8 pumpkins and felt so bad when I forgot candles or couldn't buy them ;-;
It's not so busy at the beginning, not much to do, but once you have 8 pumpkins you spend the whole day getting each one a candle and playing and cleaning each of them.
I was getting confused about the Wicked Soul pumpkins. They seem to like things that the other souls don't like and vice versa, but they are still scared of the ghosts at night, so I wasn't sure how to increase their hearts other than just letting them be.
