Since Adobe ended support of Flash. I downloaded the original files from bfdia.tv/5b. Includes Flash Player.

-BFDIA 5B

Simple timer overlay mod that displays
a) your current time
b) your total time
c) your best time for that level
This mod also shows your best time when hovering over a level button.
This mod is approved for speedrunning, and the timer overlay can be turned off by pressing "T", so there's no good reason not to just use it.
If you want to submit a run, use the GitHub release. The GameJolt release uses a different and more accurate timing method, so for obvious reasons it can't be used on the leaderboard. I recommend it for practice because you can get a more accurate best time.
