The first few days have a very small number of spelling, grammatical and syntax errors. But at a certain point, they start occurring ever third text block, and sometimes there are several examples in a single paragraph.
For example, in the scene when the MC talks with his mother in the kitchen about his doctor's appointment, there are several dozen such errors. Individually, they're all relatively minor ("no that not a problem" instead of "no, that's not a problem", "thats" instead of "that's", "shes" instead of "she's", "to" instead of "too" and vice versa, "district" instead of "distinct", missing commas, and the like) but they occur with notable frequency all of a sudden, especially because they were so much less common in the first couple of days.
Was there a problem with the proof-reading?
