Move Plus Mod 1.14.4/1.12.2 can be explained as Move is Walk and Plus is More. If you are fond of free-running or parkouring, this mod will drive you crazy.
But do you think that Minecraft has any limits for movements? Some players think why we should run while you can fly. Flying is not so fun as running or parkouring at all. If you wanna run, or jump, or flip, then you should try Move Plus at least once.
The feature Move Plus Mod 1.14.4/1.12.2 supplies for players is following here. These features apply for all version Minecraft which is above 1.12.2. These are ledge climbing (use crouch key when intending and pressing up against a ledge), ground dodging, knockback resistance, needed only on client-side.
