SizeSlider
You ever wanted to feel like and house or a mouse that lives in it, Now you can.
About this Mod
Size Slider lets you change your Minecraft player’s size with a simple in-game menu. Press O to open the size menu, preview your character, adjust your size, and apply the change instantly.
Players can shrink down small or grow into a giant while keeping gameplay simple and fun. When growing larger, your stats automatically scale upward, including reach, damage, health, speed, and jump. When shrinking smaller, your normal base-game stats are preserved so tiny mode stays playable.
For worlds with cheats enabled or server operators, the mod also includes an Admin Panel. The Admin Panel allows manual control over range, damage, health, speed, and jump separately from player size.

Server lagging with SizeSlider – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SizeSlider consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
