Well, I'm not entirely sure what to put here, as all this mod does is makes every single block in Minecraft(not other mods) slippery.
One bug that I know of is boats not losing velocity when spinning in a circle(therefore causing the server to crash). At this current moment, I'm not sure how to fix it, but I will try to see if I can find anything.
Here's a video on how it works: https://www.youtube.com/watch?v=1BVE51x---0
And yes, this is the official mod used in this video(go to 1:26 ish for evidence).
--There are 2 mods. The first one is just normal every block is slippery. The 2nd one makes all blocks have no friction at all, meaning that you will not be able to slow down without stopping yourself with blocks or holding the 'S' key for a while.
Note:
- Do not distribute this JAR file.
- Do not repost the JAR on any other site.
- You can use this mod in modpacks - no need to credit.
- This project will not be open source as it uses some hacky techniques so modify things which the community should not be using(as a general rule).
