The time that the game displays at the end should be the time from first spawn in to when the game is beat, the hearts go away. I agree as well that the in game times are a little weird on the leaderboard. It seems that "Real" time is what it is rating by and it is making rankings off.

For those who would like to use this trick or try it, here is a video where I pull it off.

So I'm still waiting to for my run to be verified, but right before I did the run I learned that I can and then learn how to "easily" (You have to have good spawns) outrun the wall generation. Does anyone know if we can use that or not. It is used in my run and I want to know for when I try to make my run faster.
