Hi
I noticed a small bug:
I had a game where I saved (called save game b)before opening the menu and leaving the computer for a few hours, when I got back and played for 20 mins ish - before saving again in a new save game (called save game
and wanting to quit, I noticed a huge difference in the time section called "played" for each game, that added up for the time the menu was open + playing time, and not just playing time in total.
In short I surgest to pause the "played" time when the menu is open 
Running version 1.03
