The Minecraft GP Extensions mod is a mod focused on extending the gameplay of Minecraft without interfering or making it not seem like Minecraft anymore.

There are lots of things in this mod, but you can get a basic understanding if you look at the captions on the pictures.
This is an alpha so stuff may be changed, removed, and most definitely added. Leave suggestions in the comments for ideas of things to add!

BETA UPDATE!:
Lots of new weapons and tools have been added! Dimensions such as the Brine, the Undersnow, and Celestia have been added.
TO ACCESS THE BRINE, use the Chlorinetine portal brick and the brine igniter in a Nether-Portal formation.
For the undersnow, use Snow and the Snowball on fire.
For Celestia, use celestial portal brick and its consecutive igniter.

Tons of new and fun-to-use weapons have been added! Artifacts that give you buffs when held also have been added!
Tons of new items and blocks have also been added. To see all this new content load the mod!

You can also find biomes such as the Brine Desert, Cherry forest, Magmatic Deltas, White Cherry Forest (Rare), Boreal Forest, and more!
Go explore it!

Not everything is shown in the pictures, so you can discover some new stuff if you download the mod!

I recommend playing this in creative mode right now, but do whatever you want! Ask me if you have any questions!

HOW TO DOWNLOAD:

Download this as a .jar file, and then pull up the folder %appdata% by searching it up in your computer
once you find that folder, go to .minecraft. Click on "mods" and drag and drop the file into the folder. Download Forge 1.15.2 and launch the game.

Maybe I will make a tutorial on how to make a mod in the future. Let me know what you think of it. Have Fun!
