Moovy

Moovy replaces parts of vanilla movement with a new system. It is meant to bring Minecraft's movement closer to traditional movement shooters, and most of the original feel is kept. Sprint jumps no longer build a speed boost, since the author found that sliding became too strong, and jumps are slightly lower with a slightly faster fall. Surfaces such as ice are a little more slippery than in vanilla.

The new movement system is locked to players wearing boots enchanted with Soul Speed, and while those boots are worn the system stays active. The mod also reduces how quickly the boots lose durability. Moovy needs Quilted Fabric API (QFAPI) and Quilt Standard Libraries (QSL) to run. It is client and server, so the server and every player need it, and it is released under the MIT License as open source for Quilt on 1.19.2.

The server notes are important: the author chose to disable vanilla's anti-cheat for movement and did not make the mod compatible with it. Server owners should expect fast, unusual movement from players, and the mod carries repercussions that were not fully secured.
