Wow, I had no idea this was originally on Newgrounds, though I suppose I shouldn't be surprised. What to say... There's really not much of a game here, but that's also kind of the point, as is the simplicity, the humor being decent but not fantastic, and basically just all of this.
Given the simple ingredients, I don't know what more you could really do here. The colored buttons, multiple buttons, and even the moving one all make this a bit more interesting, but making something genuinely difficult almost doesn't feel like it would fit with the theme of the narrator actually being quite bad at getting you to stop clicking.
Giving this an 8/10 but it really is a classic.
