Ohhh i know! i did that on Steam! Sadly, no lilith on VITA XD. I made a few runs with Isaac, rerolling treasure rooms and libraries until i got book of revelations... Sadly, with this method i always get Conquest instead of Death Steam has, since Afterbirth, many more achievements and a steep increase in difficulty. Also... have you noticed that charged attacks tend to... jam a bit? I mean, Azazel's brimstone sometimes shoots left even if you charge it to the right!
Indeed Damn, on VITA i still lack that damn Super Meat Boy secret... Are secret blocked too? Plus, one day we'll have a silly talk on Steam, i'm sure. Judging by the few words that we've exchanged, you're a very interesting person :3
