Ghost Baby's attack does not go through Mr. Shy's mask.
I'm just saying
The Binding of Isaac fangame, heavily inspired by Plants vs. Zombies · By
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:
Yeah but it might be neat to have if more floors get introduced and we get more slots to work with. Plus since you can't get all the babies in one run having similar babies like mongo, incubus and lil'delirium isn't really a bad thing. Plus having quicker access to place your main babies is never a bad thing.
add Yum Heart as an activatable that gives you a reserve of hearts at the moment and that increases every time you use it in one level, when you move to the next the accumulation of hearts will restart
I like this idea a lot! The Jacob and Esau one just being a challenge is a little weird to me though. I think maybe they could start with double baby, multidimensional baby, the deserter, and brother bobby, as well as spawn 2 copies of a baby, that take twice as many hearts. Other ones I can think of:
Maggy: Starts with candy heart, and <3, but replaces little chad with double baby. Simple character.
Cain: All active items give you a bunch of coins instead, and you can buy babies at the shop. Also starts with Abel instead of brother bobby.
Judas: Start with no chargers. When you die, you come back, and all babies turn into shadow versions. Shadow versions gain double damage, but cost twice as much and have less health.
B.Baby: Start with the poop, and replace Lil' C.H.A.D. with a new baby called The Relic. This relic takes twice as long, but gives Soul Hearts, which count as double the hearts, but take up the same amount of space in hard mode and such. Meant to be a challenging character.
Eve: Start with a new item called Dead Bird. This makes it so when a baby dies, a bird spawns that harrases and deals damage to the baby's killer. Also, All babies start with lower base damage, but deal 2x the original damage at low health.
Samson: Whenever you lose a charger, all babies gain damage for the chapter. Simple character.
Azazel: Start with a new Lil' Brim baby. All babies have limited range, but can be placed on obstacles. Starts with a unique item called "Hemoptysis", which makes monsters in a 3x3 area take double damage from Lil' Brim.
Lazarus: Revives, but after revival, all heart producers give only 25 hearts each. Simple character.
Eden: Starts with little chad, a random defense baby, a random attacking baby, and a random support baby. Also starts with either 2 random quality 1 items, a random quality 2 item, or a random active item.
Lilith: All babies are blindfolded and have a little incubus floating around. These can attack monsters on the left or right of the baby. Start with lil' chad, demon baby, a new Gello Baby, that shoots normally but whips monsters that get within 3 tiles, and a succubus that boosts the damage of babies in a 5x5 area. Start with box of friends, which summons a second incubus on a baby (and would normally summon one extra incubus on a baby for other character).
The Keeper: All babies start with their shots alternating between triple and quad shot, but much lower health (Like 6 hits from a gaper). You can spend coins to heal your babies.
Apollyon. Starts with the normal deck, as well as a new "Void" Item. All babies start with slightly lower stats, however the void item destroys a baby to give random stat upgrades to babies in a 3x3 area around it. The more the destroyed baby costs, the more stat ups.
The Forgotten: the middle 4 slots are dug up, and cannot have things placed on them. In the middle of these 4 slots is a skull linked to the soul. The skull will attack enemies that get close, and you can use the mouse to move the soul, which shoots like ghost baby.
Bethany: Start with the relic instead of Bob's Brain. Soul hearts charge up the active item. Beth starts with Book of Virtues, which summons a low damage wisp baby. The wisp baby changes depending on what active item is combined with book of virtues.
I think it would be cool if The Lost also started with Lost Soul, allowing you to actually use the 666 hearts to summon it.
I know like 50,000,000 People have said this
but you should add twisted pair, they have a lot of cool ways they could be implemented. i made some shitty concept art to give an idea of what they'd look like ingame.
Also keep up the great work
maybe the angel rooms could have their own requirements, like, having enough babies on screen when the room ends, gives better chances to get an angel room,, maybe devil rooms can be like a miniboss
That just seems like moving box, maybe make it teleport all enemies in a 3 by 3 back to the start or something.
maybe just to be worth it, stomp for a fixed damage, maybe just do 50% health damage only once per lane on each level, i don't know, given how almost the first enemies on each level on each lane are "almost always" gapers, it would give a great headstart without being op, or yeah, just completely kill the very first one
Great idea! But personally, I think it would be better that an object, a child, a monster, can only be tested if you meet it at least once in a standard game. So interest in learning content would be maintained (Translated from Google translator, I say this, in case there are errors in the sentences)
Good idea! I'm gonna try to think of the tainted counterparts of the four starter familiars you get in the game.
Brother Bobby: Shoots a lot of shoots but nearly no dmg (like soy milk)
Little C.H.A.D. : Produces less hearts but fights back
Cube of Meat: Has less health but splits into weaker Cube of Meats when killed (they dont split into more)
Bob's Brain: Explodes in a bigger range but deals less damage
The idea seems to be good, but here you need to think, because a banal improvement in the chances of a good store or heart is not interesting. It would be much better if the gameplay changed for each character in a coordinated way. And if you add, not as much as in Isaac. Because quality is better than quantity.
Hey, hello again! I have a cool unit design. He will be a "stone spectator" when the attacking babies shoot, he attracts most of the tears to himself and returns them, causing them damage. This works even for truckers. He cannot directly attack the kids. Thank you if you finished reading! Ps Lol, noticed one small jamb on the splice. Maybe I'll fix it later. 
Hi, again I have a good idea, the author of which is "Kapustinek". Alternative deck. I wasn't thinking about how to get it, I was thinking about one guy, just in case that idea was in the game. Sister Maggie - Shoots bloody tears, inflicts less than Brother Bobby, but when hit by an opponent leaves a bloody puddle that slows down and deals little damage, and disappears after 30 seconds. The rate of fire is the same. Here's the sprite and the GIF. 
I came up with a new baby. Brother Max. He has 1 unit of health, even a fly will kill him in a collision, but he has a shield, for 5 charges. When this shield breaks, Max emits a wave of enchantments that deal a bit of damage, and push all enemies to their starting point (Only works with those enemies that are on the same horizontal line as this kid). After this attack, the baby does not die, but remains until he is damaged. It costs 100 hearts, it is charged as much as the "Cube of Meat".
I threw some ideas and decided why not do something for locations…. well in the original game there are rooms well with water ,_,
you can also throw off your ideas for my answers, for example, water monsters or water babies.
(Upd) what is dark is deep water and what you see in the cells is shallow water.
Brother Polyphemus shoots huge tears, but he has a low rate of fire. Costs 150. Personally, I think that this toddler would be useful in many combos, but by itself it is not very good. For this, the price is low. 
Mom's shovel - replaces the usual shovel. It has two properties, the first of which was one discovered, mother's shovel digs a hole into which the enemy falls, and it closes, while giving 25 hearts. Second property: you can dig up one of the cells without dealing with a brother or monster. After ignition, a fossa in which a heart, a coin, a 5 coins, or a pill. But may nothing fall out. The hole is buried immediately after the object is lifted. Always damned, worth 99 coins. If a what, I translated it through a translator, so maybe there may be problems with the text. 
I have an idea for another good brother. Ghost Mask - worth only 100 hearts. It has two, even 3, new mechanics. It can only be put on another brother, while preserving the past properties of this brother. First, the mask can throw a chain, and pull the enemy to itself by 1 cell. It can do this if the enemy is no further than 7 cells, and no closer than 2. The second is complete invulnerability to the attacks of absolutely all enemies. Enemies who approach the brother with a mask, just pass through without causing damage. Mask can kill shovel only or "Altar of Sacrifices". Переведено при помощи Google translator.
Or what if:
1: it could throw itself and bounce off the enemies while slowing them and then respawn and wait a lil bit to throw again
2: it would act like the grape thingys from PvZ2 where it would explode into shards what whould bounce through the field hurting enemies but it would kill itself in the process.
and 3: it could be placed and you, the player/isaac could push it to hurt the enemies
The challenge seems cool btw.
Incubus - when the pill is applied, all the incubi present get the effect. But most importantly, the effect is saved and summed up between levels.
Dr. Fetus - works like PVZ2 coconut cannon, but with the catapult pattern; provides weak protection, equal to two ordinary babies
Epic Fetus is placed in the active item slot if there is a Dr. fetus in the deck and Doctor's Remote was selected as the active item. Works as PVZ1 Cob Cannon.
Магазины скорее всего были придуманы для предметов, а не малышей. Плюс, их (малышей) тоже много за забег можно получить. Было бы логичнее понизить шанс на выпадение монет, или завысить цены в магазине. Вот что реально нужно, это менеджмент малышей. Допустим комната Сатаны, можно купить предметы или малышей за других малышей, а стоимость работала так:
Ситуативный: один малыш
Хороший: два малыша
Мегахорош: 3 малыша.
Таким образом можно было бы избавляться от ненужных малышей, и получать нужные предметы, или бебиков. Но это также может сыграть злую шутку в будущем забега.
will act as an improved power up pill, in exchange for its use, the recharge of the usable item will be lengthened more for each use
gives you a random resource, pill, coin, mini hearts or hearts and very very very unlikely a passive or active item
gives invincibility to a baby that you choose but will avoid shooting, in return you can perform the effect to allied enemies (Gapper, Fatty, etc.) and will be given invincibility, and instead of the babies can attack.
Petrifying baby, does not attack, being placed in a row, will infrequently petrify all the enemies of that particular row for 2-3 seconds
baby scissors, mechanics based on the carnivorous plants of pvz, will attack a single frame in front of it and after attacking will have rest/recharge time to attack again
