Hi! I don’t usually comment on things, but I found some typos so I thought I would be helpful and point them out :3
Page beginning with “It's narrower than any of the previous areas.” has “exponentially” spelled as “expotentially”
Page beginning with “Oh my, that’s nice.” The wrong form of their is used in the sentence “Regular people going about there day” there -> their
Page beginning with “That’s right… you took this paper.” The word “abdomen” is misspelled as “abodmen” and the last line spells “really” as “reall”
Page beginning with “Wouldn’t that be nice” has “clicking” spelled as “cliking”
Page beginning with “As you walk down the hallway, you admire the paintings.” The word “environments” is misspelled as “enviornments”. On the same page, “equivalent” is misspelled as “equivilant”
Page beginning with “Toriel strides through the garden” has “feud” spelled as “fued.” On the same page, “believe” is spelled as “belive”
Page beginning with “You think you hear the sound of someong choking in the background, but you can’t be too sure because it’s so faint.” someong -> someone
Page beginning with “You are finally leaving the narrow cavern and at the end there's a large red flower” has “glistening” spelled “glsitening”
On the Sans route, the page beginning with “The Snowflake is a white and blue themed comedy club” there’s a line that says “red a cat-like monster” instead of “a red cat-like monster.” In the same paragraph “waiter” is misspelled as “watier”
Page beginning with “You linger in the elevator” has “wipes” misspelled as “wips”
Page beginning with “The castle is built into the cave walls” has “intricate” misspelled as “intriciate”
This is everything I noticed, I’ll comment if I find more! :)
