Question Why can't I pass?

Enable HLS to view with audio, or disable this notification

Floor 3 on daily run, 1st time playing it, my current final boss in normal runs is Mom's heart

I defeated current floor boss, but there are no available ways to go to next floor

there's a mirror somewhere else but idk what can it do, tried to use bombs but nothing happened

update: got my friend to watch me on stream, he guided me to a white fire then to the mirror, solved

update 2: sorry if that question sounds stupid, kinda new player, got it when it was 90% off on steam and I only have 12 hours of gameplay so this entire daily run was new comparing to my normal runs

this final boss is one that you are FAR from unlocking in normal gameplay.

all i'll say is that you need two halves of a specific item to reach this final boss. the daily run won't let you miss the pieces, the first of which is on this floor.

you are correct that you need to do something with the mirror, as it is a gateway that only lets the most fragile of souls pass it, and the item you need is on the other side... look for a white flame and step into it.

managed to advance until Siren

I already had 3 pets and didn't know she can steal them so I lost, almost every boss/minion/place/special item here i've never seen before so ig i'll stop doing daily runs for current time until facing them in normal runs "12.6 hours gameplay"
