(Former WR) Platypus (Easy Mode) - 48m47s
DISCLAIMER: I had to record the timer separately since recording both Platypus and the timer is essentially impossible.
With that being said, here's the first official speedrun of Platypus! There are other full runs of this game out there, but none of them seemed to be below 50 mins.
There are two other difficulties, a multiplayer option for each, and a WHOLE load of improvements to be made. I hope you enjoy!
