13 hours played, finally won today. My second time meeting Mom. The first time I didn't really know what was happening. This time she was a pretty easy boss. The real boss is The Depths.
Teleport was the star for me. I Teleported through most of Depths I, which sucked because I had tons of money and didn't get the store or the power up room on either floors of the Depths.
On Depths II, I teleported after the second room, to the room right next to Mom. I had one heart and one soul heart. I killed the four blood spewing vaginas in the room, and then used my tarot card -- I held off because I didn't know what it did. It was The Sun. FULL HEAL! Mom was a piece of cake with my 8 hearts.
I feel like I could keep playing this, but I'm gonna call it done and get on with other games.
