After failing miserably a couple times (Nope, I wasn't able to even make it to Day 2), I decided perhaps changing the keys to WASD would help. So I start out, and Bill (mole guy) calls first, and I go over there. When using WASD, my lawnmower would temporarily be out of commission... it would refuse to mow, but it would move over the grass and everything. Sometimes it would work, but then all of a sudden it would stop. There wasn't any problem with the arrow keys, I switched back while it was messing up and it worked fine.
