Wait for me to make more, I'm afraid!
Some suggestions: a.) more diversity and possibilities in it; b.) being able to load a saved game, without returning to the main menu; c.) being able to go roll back on previous conversation or action (until a certain point); d.) The implementation of switching with Abbie to save Missy was a creative idea. Maybe that could be done with a bad girl, a popular girl and a cool looking girl (like one with blue, green or purple hair); e.) more customization on what the character can wear and look like (including on the switched person, and being able to change the hair color).
