I'm a mod developer for Suraimu who has plenty of mods that ended up in the vanilla game.

A lot of my mods are on my SlimeMaster952 account but I forgot the password so I started posting my mods here

I'm not active on here anymore but I have a youtube where I post sometimes

Mods that ended up in suraimu:
-Otherworld Textures
-The Dark Slimes (removed in beta and re-added as a joke in the Graveheart fight)
-Difficulty Mode Selector
