Introduction
Ever wondered if the Debug World, having all the blocks in the game and all, is survivable? Ever wanted to break and place blocks in the Debug World? Well now you can try those with this mod! This mod will literally make the Debug World behaves like normal world (except for the world generation, of course) where you can break and place blocks at will!
1.20.1 Update
As of this update, you can now configure the mod to behave as you wanted (as much as I can make it happen) by simply clicking the Customize button next to Generator Type (or use the Mod Menu). Stuff like Iterations, Setting Grid Total Width, Gap Between each block, Changing Barrier Y level, and even adding Y axis are all possible.
Other Features
This mod also changes the "void darkness" effect to trigger at under camera Y=60 (configurable in the aforementioned config screen) to help mitigate flashing effects when you jump on the barrier floor in the Debug World.
One more thing that this mod changed is the world creation screen. When you select Debug World, all the buttons will appear and function as normal. The game mode changer button will also still be enabled.
