What? I've still got mine. Anyway, first run, NEW THINGS WOT I ENCOUNTERED ON MY JOURNEY. I only got to the depths on account of me trying to take screenshots of moving enemies.
No idea what Blood Rooms do. I tried walking on the spikes.
Catacombs...
Erm.. a nice collage...
Fortune Tellers...
Curse rooms - still no idea...
Necropoles...
Libraries...
Rooms with no destructible enemies...
New bosses.
It's interesting. What the hell do Trinkets do?
