Thanks for playing, and for losing track of time! That’s the best thing anyone can say about an incremental game.
You found the trick: once the Monthly Report is minimized, it stays down. Each new month updates it in place, and its taskbar button blinks instead of popping the window up again. You can minimize it with Esc, or by clicking its taskbar button while it’s in front. Marge in Finance insists on handing you one every month, even after the money stops mattering.
The full version is on its way, and the Steam page is coming soon. Thanks for the kind words :D
