The PA voice in the background is a cool touch. The idea of doing one small thing for someone eventually coming back in your favor is nicely displayed in the game. The gameplay itself is very straightforward and perhaps too easy, making the long distance walks in between a bit frustrating (especially the office). Merely being able to walk or sprint would have been a terrific help.
TLDR: Great idea, nicely worked out gfx and sfx wise, but not very challenging
