I love the graphics and the somehow calming effect of just doing the small tasks around the office. Reminded me of when I was an intern myself :) I was waiting for the boss to get angry because I couldn't quite finish all the tasks. I also love how you added background stories for the officemates. Perhaps you will be updating the game so they can interact with the player? That would be cool!
Some caveats. I couldn't finish preparing the meeting room and the party. I kept clicking the table and the party banners but they weren't working :/
