Thanks, and good to hear from you again! :D It's exciting to be able to constantly add to and improve it. Every week, it looks different, and it's fun to look back on all the progress that's been made.
Update:
Last week I managed to put together locked/unlockable plots and a save file that records how many plots have been unlocked.
This weekend I threw out the placeholder title screen and replaced it with a real, pretty one that includes a menu.
Next, I need to finish setting up all of the plots and create some sort of congratulatory event for when the last plot is completed. Then the game will technically be a complete game, and so I will at least have something minimal to show my coworkers. After that, I will polish the plot selection menu, perhaps add some more music/sounds, and maybe even add some new features.
I've decided I will reveal it to my coworkers on August 13th, since that will be just before some of them start to leave. It's also the day of a symposium in which many of them will be presenting on independent research they've been conducting over the summer. It seems like a solid date. It's just over two weeks away!
