Simple Jetpack 3D

This mod adds a simple jetpack to the game. This jetpack model is 3D and inspired by the 2D jetpack in the "Simple Jetpack" mod I made. So actually this mod is the 3D version of the mod called "Simple JetPack 3D" in newer versions and Fabric.

Logic: When you press the "J" key in the game, it gives a "Rise" effect along with a sound effect. It also gives a feather fall effect so you don't fall when the effect ends.

NOTE: Should I give you some news, this jetpack is unlimited.. :)
