Maybe spoilers if you haven't beat Isaac yet, just to warn you.
So i wanna get the D6 for Isaac, so im currently trying to do a ???(Blue baby) run. Its so freaking hard, literally start with just spirit hearts, and its annoying me. Anyone got any tips?
My best try was reaching Moms heart, had a book of revelations and a battery (YES) and fetus! (throws bombs as an attack). I had meat boy as well, i threw a bomb, the bomb came back at me and killed me (thanks meat boy :( )
But yeah, tips are welcome
