Ghost Baby's attack does not go through Mr. Shy's mask.

I'm just saying

I was thinking about how to do the alt floors and i thought about a level selection / progression like Slay the Spire or Inscryption, where you choose your path, i think that could give this game a new level of depth that would be perfect, and it would fit nicely with the Isaac theme, maybe you can put angel and devil deals in this choose your own path style gameplay ( i dont know how that way of selecting levels is called xD)
English is not my main language so sorry for all the gramatical and logical errors.

Maybe a magnet for auto collecting hearts or money/something that makes the duration for hearts or money longer (great game btw :-) )

i like to see challange like zombotany or vase breaker from pvz

Boss version of the Sperm Whale enemy with a name coming from one of the most famous whales of all time, Moby Dick.

Think about it. Put my man Spermy Dick in the game. 

Hey, so it would be really cool if you could add an indicator on store items you haven't seen yet, similar to where when you find a baby for the first time.

I think, what would be nice if after first loop and in hardmode we have +1 extra slot for babies.

Also I have an idea about "Horn Baby" which will be like a pit, and when enemy step on it, from pit will be spawn Big Horn's hand which take monster to the hell.

Oh, and I support idea about "Bloody Puppy" chargers, but maybe you realization it a bit different way.

add an alternate boss to Baby Plum that is set in the blue room, example: greasy blue.

mechanics: it moves inside its giant blue bagoneta where it joins or merges with it, attack 1: from there it will attack by opening its stomach and launching a whip of entrails. attack 2: will open his mouth to come out: a circle of Hush flies that last for a single tear / a blue yawn / blue boil (will summon a Hush fly every so often).

example:

Translations to other languages maybe??

Sewing machine, lets you upgrade babies (not item, more like the choice at the end of each level)

Please, add baby in ice. At first it will work like a cube of meat, but when the ice is gnawed it will work like a Bobby.

(RUS) Добавьте босса The Siren

(ENG) add The Siren boss pls

In Plants vs Zombies 2 there's a button present in the Plant Select Menu that allows you to pick all the plants you picked in the last level/round. What if something like that was added in this game? It's not a game changing mechanic but I think it'd be helpful.

some challenge ideas

Alright if you have played pvz 1 you probably remember I.zombie, ya that's the whole challenge and if people like it enough you could possible make it a game mode. if you have never played I.zombie basically the roles are switch, in this challenge you would control the monsters trying to get into Issacs house.

"Backasswards", if you played Tboi you could probably guess what this is. You will start at Ark 3/the boss fight and when you win you will go up a floor, losing a baby each time you go up and losing an item/s when you kill a boss.

"Inflation", make all heart income haled or make everything cost 2x more. and if this is still to easy, make the falling heart not appear so your only heart production is from your chads

"Get active", you get a set of 4 active items, but you have no babys so you have to survive  using only those active items. You can make it so they have half cooldown or you can choose what items you get, idk

"Pitch Black", basically everything is really dark and you can't see the enemies but you can use crispy baby, paschal candle, or anything that's on fire to provide light

"you heartless bitch", it uses the hard mode system of hearts, and you have to get to 40 hearts total before you die, and the wave you are in is endless and ramps up in difficulty.

"attack on titan", there's one huge fatty/stoner, like if you use mega mush, that's how big it would be, you have to select a team that can kill it before it can make it to the end, it can stomp on baby, killing it , and it can be hit from any row.

em I use on bobs brain speed down when he grow and then my game crush and my seed reset

¡Hey! I think adding a warning when you're going to play without a heart generator is one thing that would be cool. It has happened to me several times that I didn't realize it and lost a game because I didn't play little chad. Pvz has that system, basically a "are you sure you want to play without a sun generator?" and helps avoid these problems, which hurt especially when you are very late in the game.

idea for a new boss (based on Tboi): Amalgamation of sins. boss image (provisional):
