Thank you for the feedback!
Right now, I'm not planning any updates to the game, and I'm not quite sure if I'll ever update it at all (other than bugfixing), but if I ever do, I'll consider your suggestion! I think backstories could be nice - your particular example, +1 level of a main skill, seems too powerful, but something like a minor skill, extra cash or a special "heritage" item would certainly be possible.
