Very serious game! Reminds me of times when I worked in the office. Really helpful for practicing your screen concealment skills, so deasperately required at any open-plan office job. Five out of five.
P.S: I've encountered a small visual glitch on level 3. For some reason, the bird in the minigame was displayed with the thin green line (healthbar?) beside it. When I restarted the level, it disappeared.
