Ummm there's likely a guide or 2 for how to enable mods for the game. I'll copy/paste the one I found on the Discord, it should be accurate:

How to install mods

• Download the zip file of the mod
• create a "mods" folder next to your game executable
• unzip the mod inside the mods folder
• check that there is no nested folder inside the folder of the mod with the same name
• Start your game

• Click on the mod editor in the lower left corner of your screen
• Activate the mod by clicking on the crest right of it

To be a little more clear on the file structure, it should look like:

Ero Dungeons game folder -> Mods -> Shiny Things -> mod_info.txt

and NOT like:

Ero Dungeons game folder -> Mods -> Shiny Things -> Shiny Things -> mod_info.txt

Hehe, that was the item that spurred me to make the whole thing in the first place. Irony is, I cannot get one for the life of me in my own game!
