About this Mod
This project adds a random jump height to every jump.
This makes gameplay unpredictable and chaotic, turning even simple movement into a fun challenge. It’s especially interesting for parkour, survival, or challenge runs where precision and adaptation matter.
Before downloading, keep in mind that movement will no longer be consistent — every jump is random, so standard parkour strategies may not work as expected. This mod is designed for fun, challenge, and experimental gameplay rather than normal progression.
