Give me ideas, and I will make it.

demonic little grey cat boss fight

with a noteblock music in the background of the same name -(look YT)

extremely hard but possible to kill solo . 

make it anti farming

the ultimate cringe weapon:

make an OP sword with 32x32 texture that looks insane

something like these:

make it take half of a mob's current health value every time it deals damage

make it if a mob has 1 hp it insta kills it

also make every other stat extremely low, like: durability:50, enchantability:2

make it drop by the idea above me

name it something wacky like: "sword of the forbidden arts", "forgotten blade of furious warriors"

(I don't know if some of the mechanics I've listed is possible to do with mcreator, so if not just leave it out.)

a keybind that, when pressed, gives a poisonus potato

A mod where you can jump

a mod where if you press the e key, it teleports you to the EEEEE dimesion that is a void and EEEEE structures spawning, and the only way to get out is to die

A mod where, when you press the [7] key you teleport to the nether lol!

a mod where you have to fight a giant creaper instead of the enderdragon

A mod where forward is backwards and left is right.

Good afternoon, I would like to suggest an idea for a mod, I tried to create it myself using MCreator, but nothing worked out, I couldn't write the code that brings it to life.
I've also tried other programs for writing codes for the mod, but I'm not very good at code.
What's the idea anyway, I wanted to create a mod that adds an additional player to the game, whom you can direct via chat, or if it's still possible, using voice chat,
Which in turn helps the player in many things, like going for resources, building something, traveling together, etc.
