Samson won't unlock when beating two levels undamaged.

[who peed my pants]

Ok so i've been playing a level (ETASFN78) repeatedly in order to get Samson. I have beat the first two levels without getting damaged three times and I still won't get the achievement. I have played this twice as Lazarus and once as Issac. I am going to (in detail) explain how I beat the stages, so maybe someone will see what I did wrong.
Firstly I get the daddy longlegs item from the room right to the starting room. I ignore the rooms up and down. Then I get to the room to the right and the leg kills the enemy to the left while I kill the enemy to the right (two of the times I have completed this I have been able to get the right enemy to blow up on the cross rock, getting the gold chest, which I open after getting the first key.) Next room (to the right) the leg kills the left enemy while I kill the two flies in the middle and the enemy to the right. Then I proceed to the room down from me while the leg kills one of the flies while I kill the other one. Then I go to the boss room, kill famine, get the steel heart, and get the ball of bandages. I go to the next floor. The next floor has the curse of darkness which made it the a tiny bit harder. I collect the scapular from the room to the right. I go back to the main room and go down to the next room, kill the enemies, and go to the room to the right, kill the enemies, go to the right, go down, avoid the moving spikes, and go to the room to the top right. I kill the enemies and go to the boss room. Once again I kill monstro, collect the rotten meat, and I ignore the devil room (if it appears.) I go to the next level and nothing happens. WHAT AM I DOING WRONG. IM I JUST STUPID?

edit, i just unlocked samson. I stopped using the seed.

You cannot unlock anything using a seed.

Edit: Oh, btw., you can take devil deals or donate blood in a blood bank or to the blood beggar, that doesn't count as damage for unlocking Samson.

Ok. Thanks

edit, if you loose health from a pill does that also count as damage?

I think bad trip does, since it ruins devil deals. It's only two levels, just don't take pills until you get to the caves.

Yeah, bad trip does count, health down doesn't.
