The use of second person perspective makes me quite happy with my own imagination, I don't need to feel like someone else. Too bad you didn't elaborate on the populace of Snowdin nor the mermaids. Chances wasted :( The scattered description could use some more foreshadow... I thought Muffet was as big as DotA Broodmother before I got confused with how six pair of hands could fit on a shoulder.

Overall, great!
