I thought this was great! I really like the vibe of everything, and how you need to dig through your notes for answers, and properly manage your time to get everything done. A couple things that I think would be nice though, were that I felt like the day went by too fast....just slightly. I felt like I needed to be a hell of a typist in order to answer every email every day. Maybe you could be partially penalized for typos?
The sounds for the emails coming could have been a little more obvious. When I first started the game, I thought they were goldfish at my desk or something. It wasn't until I had the emails open that I realized it was the sound for incoming emails.
But yea, this was a good time. Congrats!
