About this Mod

Mod Discord URL

After many user requests, I am beginning to slowly migrate my past projects over to Modrinth from CurseForge where they've lived for years. This was one of my first mods I coded in high school for college apps!

Double Jump Mod

Ever wanted to leap over a fencepost?

This mod simply lets you double jump in midair and shallow water. Jumps respect hunger mechanics and will decrease saturation first, and then your hunger. Values and other effects can be configured in a config file.
