This game is rubbish for exactly the same reason IWBTG is rubbish, trial and error gameplay.
Trail and error, that was my first thought as well. The problem with this is that it's punishing succes. Every time the player gets a new idea on how to solve the game and tries it out, the game immidiately slaps your hand away and tells you to do things differently. That doesn't merit reward for exploration which is part what of the interactivity of the experience is supposed to be about. And had your game been longer, it would have meant that the player would end up just running straight ahead every time without being creative for him-or herself and rather just waiting for the game to show which path should be taken.
A technical mistake is that after I've "finished" the game, you get the chance to try it again, but then if you jump straight into the floating block (the side, not the top) on the next try through, the game just freezes.
Speaking of "the side" of the that first box - having the spikes pop up when you do much as brush against the side of it, they don't actually seem to go through the girl, so to speak. It just looks odd.
Also the fact that there's such a violent different between horizontal and vertical speed is rather jarring. I for one, tend to run forward faster than that I jump upward. I know it's to compensate for your time interval, but there were other ways around that.
So taking all that into account, I can only really say its length was a rather good choice, because after playing it I didn't feel much about it other than a "meh" kind of thought. Had it been longer, it would have been absolutely aweful to keep playing.
As for your sense of humour, I don't really see it. It might have had a different emotional effect if you hadn't told me about it before hand and let me find out what this was about by myself. Also, the fact that you're probably going to die multiple times on your first try through, means that the ending is less shocking, than is the case in say, "Freedom Bridge" (you should try that, since although it has little narrative, you get at least some reason why you should care about this little black dot).
Oh! Almost forgot! Sound. Something I thought of when thinking of Freedom Bridge, is that its sound is more befitting, even for such a simple flash game. In your game it sounds like someone's just popping baloons with a pin.
Well, I hope you have something to work with. ^.^
