Cool idea. The "om nom nom" sound and the "Went to work: - Happiness" both got a laugh out of me. I did two playthroughs: "don't go to work" and "only go to work and grow tree." I got evicted in both, but at least I had a nice tree. Didn't really see where the Happiness stat came into play, though. I think I got fired in the "don't go to work" run, but the text flashed by too quickly for me to actually read. As the tree grows, it also covers up the text on the screen in the backyard.
Congrats on finishing your first GWJ!
