On the last version of DLS, which was some time ago, I added modding capability to that version of the game. Though all of the features I wanted that I modded in myself have been added to the base game in the latest version, I might as well take a few minutes to add my latest version of my mod loader to the latest version of the game.
I made an itch.io page for my export of the game with the mod loader included. Link: https://chazzwazzler.itch.io/dls-moddable-build. Instructions and (kind of) documentation are on the page.
If you run into any problems, want additions to the mod loader/utility stuff for this game specifically, let me know!
