Thanks for playing our game, and am glad you enjoyed it.
Probably should've had an introduction before we pushed you into the game, but the Green progress bar is for work done for the day.
Each day has a quota where the player must complete a certain amount of work, and not filling that quota leads to an overtime game state where each time you get work done, it taxes your sanity even more than usual, and the interactions between you and other characters change to.... nightly ones.
Cheers m8!
Enjoyed checking out your game too!
