I'd love to see this ported over to 1.14 when you've got the time, 1.12's not being supported anymore, and apparently Forge 1.14's supposed to make updating to newer versions of Minecraft much easier once all's said and done.
I myself might stick around with 1.12 for maybe a bit longer, if only because all of the large mods I play have yet to update to 1.14, so try not to rush your coding too much if you do decide to port stuff over.
One of the TNTs is 100000x bigger than regular TNT and makes a 10000x10000 crater!*
*At least 32GB of ram is recommended to be dedicated to java to run it and it lags for a long time.

Ok everyone, this is a remake of my Super TNT Mod for 1.7.2. It currently has 56 TNTs. Below is a full list of all 56 of them and a description of what they do. It is also the closest you can get to having the Too Much TNT mod on 1.12.2.
For a more detailed description including recipes and screenshots, go here.
Large TNT - About 5x bigger than the regular tnt
Massive TNT - Around 200x bigger than the regular tnt
The Super TNT of Mass Destruction - Makes a huge crater. If I had to guess, I would estimate that it's 5000x bigger than the regular tnt.
Doom TNT: The Gold Plated Plutonium Alloy Coated Eight Volume Nuclear Donkey Edition - This one is 3-5 times bigger than the Super TNT of Mass Destruction.
The End TNT - The One To Rule Them All - This one make an enormous hole.
Black Hole TNT - this one makes an even bigger hole. To reduce lag, it makes a square crater and not a round crater. It's a 1000x1000 hole.
Anti-Dimensional Singularity TNT - Makes a ludicrously enormous explosion. It's 5000x5000 blocks.
NO - Makes the biggest explosion in the mod. 10000x10000 in size.
The Biome Buster - Turns your biome into a post-apocalyptic wasteland.
Cluster TNT - Spawns 100s of regular tnts everywhere.
Super Cluster TNT - Spawns some Cluster TNTs which then spawn bazillions of regular tnts everywhere.
Heck TNT - Turns everything into a nether biome.
Fire TNT - Makes fire go everywhere.
Snow TNT - Makes snow go everywhere, freezes water if its close enough.
Ocean TNT - Makes an ocean. Works 10000000 times better and more efficiently than it did in the old version of the mod.
Sponge TNT - Can be used to soak up a large body of water. Must be submerged in water to work.
Lava Ocean TNT - Does the same thing as the Ocean TNT except it does it with lava.
Diamond TNT - turns everything into diamonds
Diamond Nuke TNT - more op than the Diamond TNT. It's serious stuff.
House TNT - Spawns a house
Bunker TNT - Spawns a house made out of obsidian
Mob TNT - Spawns a random mob. Withers and Enderdragons won't spawn from this.
Mob Swarm TNT - Spawns 700-800 random mobs. Withers and Enderdragons won't spawn from this.
Atomic Mob Swarm TNT - Spawns ~1500 random mobs including withers. Enderdragons don't spawn because Minecraft 1.12.2 has a bug where spawning enderdragons doesn't work properly.
Anti Mob TNT - A TNT that kills mobs but doesn't destroy terrain
Arrow TNT - shoots arrows everywhere
Tree TNT - Spawns a tree
Forest TNT - Spawns a 100x100 forest
Tiny Island TNT - Spawns a small floating island.
Island TNT - Copies land around it and pastes it around 30-50 blocks in the air.
Nostalgia TNT - This will make you feel nostalgic
Everything TNT - Spawns everything in the game randomly all over the place at random. Quite dangerous.
LGBTQQIP2SAA TNT - Makes everything rainbow.
Trump TNT - All this does is build a wall and make the villagers pay for it.
Kim Jong TNT - offends North Korea and starts WW3 irl. The most dangerous TNT in the whole mod. Screenshots can never be posted or shown for safety reasons although it is in no way offensive or obscene.
Is it Christmas TNT - Tells you if it is Christmas or not
Crappy TNT - This one is crappy.
Really Crappy TNT - This one is really crappy.
Cheesy TNT - Turns everything into cheese and then proceeds to play a song about cheese on a jukebox.
Flat TNT - Flattens everything around it.
Mining TNT - Place this underground to make a flat cavern with torches to illuminate the place. Useful for making a mining shaft or something.
Rake TNT - Plows a large area of land
Time TNT - Changes the time to day or night
Weather TNT - Toggles the weather between clear and rain (or snow if the biome supports it)
Lightning TNT - Makes a ton of lighting go everywhere.
Crack TNT - Makes a huge fault line in the ground that goes all the way down to bedrock.
Weed TNT - Spawns weeds, grass, saplings, sugar cane and other random foliage everywhere.
Fact TNT - Tells you a fact. Facts given from the Fact TNT may or may not be 100% correct.
Cave TNT - Makes a cave
Save TNT - Saves your game
Wave TNT - Causes a tsunami wave
Airborne TNT - Spawns weeds, grass, saplings, sugar cane and other random foliage everywhere.
Jail TNT - Spawns a jail and then teleports all entities and mobs including the player into it.
Teleportation TNT - Teleports all entities and mobs including the player to wherever it explodes.
Warp TNT - Warps each player/mob/entity to a random coordinate in the map.
Atomic Diamond TNT - Makes a gazillion diamonds go everywhere, engulfing everything in its path. Incredibly op.
Atomic Lava Nuke TNT - Makes lava engulf a large area of the map. Pretty much the same thing as the Atomic Diamond TNT except with lava instead of diamond.
Here are some videos I made about it.
18 minute video demonstrating many of the different TNTs and what they do:
To play this mod, you need to be using Minecraft 1.12.2. Forge also has to be installed.
In order to prevent your game from crashing, you should probably use at least -Xmx3G for your launch arguments but I recommend -Xmx8G if you have the ram for it. This mod does take less ram than the 1.7.2 version and lags less but it still helps to have a good computer and have java properly set up.
Note that the "No" TNT and the Anti-Dimensional Singularity TNT need at least 8GB (recommended 32GB for the "No" TNT) to not crash and it will take a long time to explode. The Black Hole TNT takes a long time if you don't have a good computer. Everything else is reasonable and barely lags on reasonable machines.
