I also received my order today. The package says it contains 73 pieces. About 30 of them would fit in a 2x2 square but almost none of them are actually "Halloween". There are a few spiders and ghosts, some candy pieces but most in the size you want are just colored stars. The cute costumed kids and decorated houses, etc. are all much larger. The paper pad has a couple pages that have squares and some of the houses that would fit in 2x2 squares also. It is a sweet set and I really like it, but it probably isn't going to work for the size you need.
