Flash says goodbye
Like Caarda said before, under the resources tab is a downloadable file named "Download Version" that is used to play the old (original) version of Duck Life. This is what the "No Major Glitches" and "Glitched" categories use, while the "In Browser" categories use the Unity version, which is what websites such as Coolmath support now. So to answer your question, the world record is beatable since we can still play the original flash version via download.
