Changes many sounds to similar sounds found in the files of The Smoke Room. Alters a significant portion of the game to make you feel like you're exploring the horrors of Echo in the shoes of Samuel himself whether you're venturing down the mines, walking around town with crunchy gravel underneath your feet, or just enjoying the background music. Almost all songs have been replaced, very few of the originals remain!

Door open
Draw map

Simply extract the mod folder into C:\Users\[​YourUserHere]\AppData\Roaming\.minecraft\resourcepacks and turn it on by opening the game, going into Options > Resource Packs. Should work even if you're told it's not for the appropriate version (compatible with 1.19, no guarantee for other versions).

This will likely get tweaked and expanded in the future.
