hi there is a mod to speed up the game to 2x, 4x, and etc
but this make the player run fast as duck
maybe a mod to slow down player speed, configurable

thats not what this mod does

'As always, if you have a mod idea, let me know and I can look into it.

because you said it

Oh yes yes i see. You're wanting a mod that slows down player speed while the game is running, similar to speedup mods? Or are you wanting a speedup mod that also slows down the player speed

This mod might also do what you're looking for

yes but this is aditional speed, i need a lower speed for the character when the game is like 6x speed, so de player model, dont get easy stuck on things everywhere

Try setting it to a negative number, like -0.3 for -30% speed
