Hey, in case no one's given you details yet, I had the same issue with the game crashing. It happens at the very end on every path, right after the line "It was home."
An exception has occurred. While running game code: File "game/script.rpy", line 240, in script call call creditroll from _call_creditroll File "game/script.rpy", line 2486, in script pause(5) File "renpy/common/000statements.rpy", line 375, in execute_pause renpy.with_statement(Pause(delay)) Exception: Style 'credits_box' does not exist.
I liked the game a lot, by the way, it's really cute :D
