I have no coding experience what-so-ever, but I would like to make a mod. If you would like to help with this mod, comment below.

My Ideas are:

+New Dimension: A black background sky, no day/night cycle. It would have Void-like particle effects and the player would need to craft a special suit or once they enter the portal, they would die upon entering the dimension. There would be new mobs: GreyMatter, they would be small grey blobs that would go around leaving a grey translucent slime trail. Similar to that of how a snow golem releases snow wherever it walks. There would also be Darksides, They would be steve, but with inverted color-schemes. Also there would be black creepers which would be rare and have a larger explosion radius. Lastly, there would be black jellyfish that can fly...I havent thought of a name yet...they are passive but if you attack one then all of them come to hurt you. They shoot black fireballs and move very slow. A new ore could be found in the overworld, its called orichalcum, its a sea-green and is rarer then diamond, but once you get 10-14 you can make the Void-like dimensions portal. It would be in the format of the Nether portal.

Thats all for now, and dont forget to comment!
