For no particular reason other than a bit of annoyance at the difficulty of this game
(actually I got through, because I think for some reason my home computer was playing it a bit below speed) and because I actually like "flap" mechanics (see: Joust, and Balloon Flight), I made a parody mashup of Flywrench and my own Atari 2600 JoustPong in the thrill-a-minute world of: flywrenchpong
(You can also play it online).

It also features a homemade electronic soundtrack! (Made by slowing down and "wa-wa'ing" an Atari 2600 Supercharger .wav)

I think if I died tomorrow, the # of people who "get" the joke because of familiarity with both indy game flywrench and atari homebrew joustpong would go down by about 33%.

And yes, I made this exact same post nearly on TGQ and indygamer.blogspot.com.
