Just because you understand the individual components of what you're parodying and why they work, and even understand what about it works to parody versus what wouldn't, doesn't mean that your parody itself will actually be any funny, nor any good. The main component that seems to not be understood is that the original was nearly over-the-top already with its philosophizing and heavy commitment to a broad spectrum of viewpoints, but still earnest about itself. Going the opposite direction completely into juvenile humor (minus one audio log that nearly fully understands why the original logs at least work for people) isn't too effective, and is also why the ultimate punchline of the game isn't effective at all.

Also, having poor hand-eye coordination or hands that end up shaking every now and then can actually make the game more frustrating and difficult to play than The Witness itself! That in itself would almost be funny in an annoying way if the game itself were entertaining.
