I found some names changed last time I played the game and fixed everything. In addition to problems with pronouns (at one point I used "his" for Megan, for example, things like that).
What I noticed is that my English gets tremendously bad when I do things in a hurry. For example, I barely released version 0.6.5 but already found things that will need to be rewritten to version 0.7.0 at Megan's house.
I chose this name because it's super easy to write and I didn't know "Bob" is a name that English speakers don't like. It was the number one complaint about the game, so I changed it to "Robert" and gave the player the option to choose the name he wants (as long as it's under 11 letters). In the end I think it's better this way.
Curiosity: The title of the game "High School Tutor" is a placeholder and I was thinking of calling it "Bob the Tutor" (lol), but I guess now I won't change the name of the game anymore.
