Idea: like pvz there could be special things that need 1 thing to be placed first (example winter melon in pvz 1 or cob cannon from pvz 1 which needs 4 plants or just a idea i has of kinda mixing things like placing icicle baby on cube of meat to make cube baby) and that you would get them from the thing at the end of a level (except for boss i guess since thats a shop)  also a good idea would be to perhaps nerf the stone poop enemys (i forgor what they are called) they can easily destroy a row of stuff if you dont got something ready for them (examples: red/blue candle or i think the thing called red maw)

also another idea: more champions, grey ones have less hp than normal but are a bit faster than normal, the one with a crown above its head will have enemys get one square closer to it (example if a enemy was above or below it would now be in the same lane and would drop a amount of stuff like hearts and coins) killing a yellow one would drop a small battery that would take 5-10 seconds off of a cooldown (based on how long it takes to charge) black ones would explode doing small damage to everything near it (including enemys) white ones that walk through any of the babys and cant be hit by close range attacks (like the thing i think is called red maw also would drop a chest containing some stuff) grey enemys that attract tears to them and drop a bomb on death (a bomb would explode after a while and some enemys might be able to throw it a small distance that hurts anything near it including other enemys) and a special eternal version for bosses and enemys that do whatever you think they should do (new attacks, attack buffs, more hp, armor even?)

If there will be new pills, I want to suggest that in each new loop, there would be only 6 randomly chosen pills that will be appearing. Preferably 2 negative pills and 4 positive.  Also if there will be more negative pills, would be nice to have a passive item that would allow the player to use the pills on the enemies. 

добавьте как в pvz 3 за каждую собранную линию в конце двали бонус , например двали 1 дополнительную монету .

As for the mobile game, I would like there to be a little more optimization, since having so many entities in the same place the game starts to go a little slower.

Игра просто супер, можно добавить после первого босса мини-игру в нечистотах где надо не дать потерянному умереть..? А в шахтах тоже, что то похожее, но только с тенью матери.

It would be cool to see a feature that would be given for some kind of achievement, like the whole style of the game changed to the style from Flash Isaac

i think making classes that have an item at the start, like isaac, cain etc.

I know you probably don't want to copy PVZ, but I still have some ideas based on the old Isaac game ideas.

1. Add a hero baby, which can be your meat boy, Isaac, or the hero in bangbang. This hero baby can only be summoned once per level, but its ability is quite powerful. To balance the game, baby heroes need to be unlocked in specific ways.

Summoning a hero baby will cause the hero to come out of the door on the left, go to the right and fight to save the situation, especially when the player is at a disadvantage.

2. Bad drugs seem useless, and we should have other ways to use these drugs.

3. Treasure: Small dice, which can convert a turret designated by the player into a random turret of the same level. Big dice will randomly convert all the player's turrets into other turrets of the same level.

4. Promotion: Players can spend a lot of money to strengthen their turrets and make them stronger. The normal turret can shoot two tears, the mortar will randomly attack multiple targets at once, the meat block turret will turn into a meat boy to bite others, and the spiked head will be able to heal itself. etc.

5. I hope the vomiter's shape can be redrawn, he looks too much like minions.

6. New enemies

According to what I thought of in the Binding of Isaac:

Ripper: If the player kills him, his headless body will turn into a sprint or jump method to quickly charge the player, but he has very little health.

Knight: An elite who is completely immune to frontal attacks. He is only afraid of penetration, ghosts, ground thorns and melee. It is a very difficult monster in the later stage.

Meatball: He will restore the health of surrounding units by 1 tear level every few seconds. If there are more than one, he will restore it multiple times.

Blood Corpse: After being killed, it will turn into mud and resurrect. After being killed, it can only be killed by thrown weapons, ground stabs, and melee. It will flee after being killed multiple times.

Skeleton: It can only be damaged when it is moving. It cannot be damaged or hit when it is not moving. Will automatically absorb fire from "thrown" weapons, but is afraid of horizontal fire.

Long-Legged Spider: It's fast, immune to ground stings and able to get over any obstacle, but is easily killed by fire. He may be difficult to hit with a thrown weapon.

Mom's Eyes: If not repelled in time, a turret will be killed with a Mom's leg trample.

Roshan: moves slowly and is very durable. He will continuously release as if to attack the player's front line. And will crush any turret that stands in its way.

Round-headed Worm: An enhanced version of the Vomiter. It can only be attacked when it leaks out of the ground. If it is not killed, it will attack the player with bullets behind it and then hide underground. He has less health than a vomiter.

Wailer: If the player kills this monster, it will cry loudly and then die, and the surrounding enemy units will be supported by an acceleration. (The shouting skill of the first BOSS)

Leech: Appears after killing a random "elite" enemy, has little health, but is very fast.

Skeleton Boy: Every time he moves one square, he will throw a bone attack, which is slightly more powerful than ordinary enemies.

Black Goat: A very difficult enemy. It will charge quickly and has relatively strong health. At 25% health, it will enter frenzy mode. If you cannot kill him at this time, he will release brimstone fire to attack a row after a few seconds. All turrets. Each black goat can only release fire and brimstone once per life.

New ideas:

Mom's Knife: One hit will kill the enemy in the designated square，CAN`T KILL BOSS！

Martyr: All turrets have temporarily received increased firepower.

Monster Manual: Summon a random monster at a designated location to help you fight.

Attraction: Pull enemies in the upper and lower rows into the same row.

Mask of Shame: Summons an invincible mask at a designated location, which will disappear after a short stay.

Workbook with tampered names: Randomly converts enemies in the scene into elite enemies, dropping pills and money.

Graduation photo: Summon a row of ghost babies from the right to attack and disappear after a while.

Vicious loophole: Convert all deployed turrets on the field (including ?? and I`M ERORR) to random turrets.

Leather Picker: Summons several poops at random.

Sacrificial Dagger: Use on a turret and it will become a worm and dash forward.

curse:

I`M ERROR: An "I`M ERROR" that cannot be killed, sacrificed, or transferred away by the player will appear randomly on the map. He will occupy this block and cannot be used, but enemies can move past him.

turret:

Rotten Tomato: Throws a liquid and pollutes the ground. The liquid will not cause direct damage to the enemy, but any enemy who steps on the green liquid will be damaged. It is very suitable for AOE and against Skull Cap.

Healing Baby: Healing Baby will heal the surrounding turrets in a 3X3 grid. It is expensive, but worth it.

Fire and Brimstone: Fires slowly, but is powerful and can penetrate all expensive babies in front of it. YES! He is too expensive!

Beggar Baby: Automatically help you recover gold coins on the map, but he will keep a few for himself.

Sworn Guardian: He will place a protective shield on random turrets around him every once in a while, or it may be himself...

Epic Dr. Fetus: Corn Cannon...yeah!

Bob: Throws a bomb head forward, but the rate of fire is very slow and there is a shooting distance. If there are pellets to enhance the firepower, the bomb will become an incendiary bomb.

Parasite: When a bullet passes through it, it will split the shell into two and send it to the upper and lower channels. But the channel it was in had no firepower.

Rotten Babies: Will automatically spawn flies to hit enemies, much faster than eggs. Although flies have little health, they effectively make up for it with numbers and have special restraint on whales.

Incubus: It will fire bullets from four adjacent turrets around it at the same time. If it is not adjacent to an attackable turret (including shadow, self, parasite, etc.), it will not attack.

Shopkeeper: Will not attack, but will automatically give you money over time. After strengthening the firepower, he will give you better coins.

Insanity: Gives random buffs to surrounding turrets every few seconds.

Idk if this is in the game but a golden pill and horse pills would be cool

more income producers, more slots and middlehorn fix cuz it crashes after middlehorn

There is no need to worry about him, he is just busy man with other stuff to do, just keep your patience and wait for updates (i cant leave more information)
