I love all the design choices in this game.
Highlights: main character looking so small near the boss; main character classic office look (great little hair in his dreams, also); punching the computer to make it work; the fact he just spills purposely the cup in the checkpoint; the fact that there is an explosion effect when you loose a minigame; the whole scribbled look of the game (very flash game-esque, and nostalgic).
Also love all the coffee themes and the little stories told in the reports. Also the endings, although I only managed to get the bad one.
The final minigame is a little morbid.
