Is there a lorereason why once you get to the uterus Everything does one full heart of damage

I'm so tired of losing runs because there's 20 rooms before the boss with a shit ton of enemies and I get down to 2 hearts and then that's just it for my entire run. I'm so tired of losing entire runs Because once you get to the uterus let's cut your hearts in half for no fucking reason i hate how everything so incredibly easy right up until you get to uterus and then every enemy is shooting brimstones. Beams that go through fucking walls A million projectiles don't worry, they're doing more damage to now that's what pisses me off the most. I get no hearts in the u to yours ever fucking ever. I've played this game. I played at least a 100 runs And every time I get to the uterus, i'm lucky if I find one heartv and call the skill issue that I'm not able to beat the entire game without getting hit and you're supposed to play this entire game without getting hit once and if you can't, you're shit at the game I don't care that you're gonna say that there is no fucking reason why every enemy should be dealing A Full heart of damage no fucking reason. There's no fucking reason at all. I can't think of a single fucking reason. Why every anime should be dealing a full heart of damage? As soon as you get to the uterus, it makes no fucking sense. If that's the way it's gonna be. You should do that through the entire fucking game don't give the illusion that you have leeway for mistakes don't fucking care that you're gonna blame it on skill I want some leeway to make mistakes i don't want my entire fucking run to be ruined Because I got hit once in the uterus everything takes thirty shots even when you have maxed damage i'm almost 100% sure. Once you get to the uterus, your damage goes back to one cause I've had max damage and it still still takes the same amount of fucking shot to kill something. Once you get to the uterus, they're like. Let's buff everything to an extreme amount
