Please do not continue to be awesome and update this game. At this rate you are going to start an epidemic of people sitting in front of their computers watching their money tick up so they can buy just one more tier of newspaper upgrades. After each upgrade they'll only think, "Oh I'll just wait around for one more upgrade. That won't take long." Slowly we are all going to waste away and the last thing we will see is numbers ticking away in front of our eyes. Vast swaths of the population are going to die out and the only thing that will be to blame is AdVenture Capitalist...
Jokes aside, don't stop being awesome developers. You guys are amazing. Keep this up and you have a fan in me (and probably thousands others) for the rest of your developmental life!
Possible fix to the offline mode: Click into the Unity window when the game is loading. The offline accumulation doesn't seem to work if the window isn't in focus.
