The clock on the level progression screen?

[☽.Silver Wolfe.☾]

I've been curious when after you beat a floor's boss and you drop down to the next level, there's a little clock when Isaac's head moves to the next floor. I've tried timing the space bar with it but I've not seen anything happen.

Anyone got a clue what it is/does?

I heard players can get a bonus if they speedrun a level/whole run. I'd assume seeing the clock on your next level means you'Ve cleared the previous lvl fast enough to get something cool on this one/continue your streak on the one you're about to start.

You unlock the Boss rush challenge room after beating Mom in Depths 2.
Just a heads up - the achievement to clear it does not count if beaten on a challenge run. (e.g Head Trauma, Purist etc..)

I've been wondering about the same thing. I stil don't understand what the clock means...

The clock represents how much time you have to make it to boss rush. It takes it twenty minutes to reach the end of Depths/ Necropolis II, so you have twenty minutes to beat mom in that level before the door to boss rush closes.

aaaah lol no wonder im not progressing any further, i've unlocked it lives and killed him a couple of times but no matter if i kill satan or isaac im not getting any new endings or floors. guess i won't be taking my sweet time on the next run then :)

Have you killed Satan and Isaac 5 times each? Because you should've unlocked the Polaroid and the Negative if you had.

But yeah, Boss Rush can be difficult to get even you are trying to because you are at the mercy of things like floor layout and such. For example some floors will start you off near an edge and have a nice linear layout which allows you to easily find everything and clear the floor quickly. Othertimes it starts you in the middle and has branches leading everywhere, if you head one way you could spend heaps of time working on that way only find out that the boss room is on the other side of the floor and you've wasted time you don't have going in the wrong direction.

I find that unless I am deliberately going for Boss Rush I am only usually defeating Mom at the 30 to 40 minute mark; or 10 to 20 minutes too late for Boss Rush.

yea i'm usually on the 30-40min mark too but then i'm exploring every room. since i found out what the clock was i haven't had any problems with the time but if you get the wrong items you won't get far.
yea i had to look up how to unlock the dark room and chest floors. i've unlocked the polaroid and got one time left on the negative.

its sometimes hard to know what to do to progress without googling it.
like
beat mom 11 times
beat isaac 5 times
beat satan 5 times
the save file picture is unreadable (at least to me) until there's only 2-3 pieces left.
are there more objectives like these?

then you have killed isaac/satan while using a seeded run - that doesnt count for unlocks
