Cute little game! The visuals are well done and the music is nice, so the general atmosphere of the game is pretty good! The story and the little jokes are also a nice touch ^^.
My main complain about the game is that in terms of pure gameplay, there is not a lot to do ^^'. Yes, the character can walk, jump, push crates, but there is no real interaction or meaning to these actions. At the end, we can choose which ending we want, so it means that the whole game doesn't matter, and walking and jumping doesn't influence anything ^^'.
I would have liked to earn my ending. What if, for exemple, I had to "not look" at all the "wrong" things, and the ending report would be calculated from the amount of "wrongness" I've seen during the inspection? For example, the closer I go from the sleeping guy, the more the "wrongness" will raise, so I would need to find a way around it? Now, walking and jumping have sense, because they allow the player to get a different ending depending of how good he perform using these actions. That's just a silly example, but my main point is: every action the player can do must make him advance towards a goal, or the action is meaningless.
So yeah, overall I can feel that there is a lot of work in this game. You created a nice little experience, with cool visuals and music, but you just need to nail that "interaction" part that will engage the player and make him feel that he's in control of what is happening. Everything else is nice, so you're *that* close! Keep doing games ^^!
