Originally there was a lot more stress to the game, but I wanted to keep it a slow experience on purpose. My friends kept suggesting an "Expert" mode, where the plant dies a lot faster and the ads would spam. You'd get viruses that required specific conditions, etc. but I didn't have the time for it. I think another reason I didn't do this was there were some issues with windows causing dead zones which made it frustrating to try to navigate a surplus of windows. In a calm game, this can be worked around. In a stressful environment, there can be a lot of annoyance to the irresponsiveness of the windows.
