The time I submitted treats hitting that green guy in the end as the final frame. Since my character touched the last platform a little bit later, feel free to retime my run if touching the last platform (not the last successfull jump's result) is mandatory to be the last frame of a run.

Mod: Time starts at 4.038 and ends at 9.491 at 53 fps to get a final time of 0m 05s 453ms. Retimed using Slush Puppy's Retime Tool
