KillsMoreSize

Each player begins at 0.1x scale. Every living entity the player kills adds 0.1x, up to a maximum of 10.0x. Kills are not counted separately for each player: one counter covers the entire world, so when anyone in the group kills a mob, every connected player grows at once. Players who join later start out tiny again, and the growth is kept through relogging, death and respawn.

The scale changes how the game plays. Below 0.5x, even a fall of one block hurts, which makes small characters fragile and rewards careful movement. A multicolored status line above the hotbar lets players read their kill count and size at a glance, and an optional growth display can be turned on or off as a preference. Chat announcements report each kill to the whole server. The mod was made for co-op play with friends and draws on the idea of a video in which more kills make the character bigger.

The mod is client and server, so the server and every player need it. It is published for Fabric only, for game version 26.2, and requires Fabric API. KillsMoreSize is released under All rights reserved and is not open source.
